Summary

Port of #5094 to v3. Supersedes #5298 (addresses code review feedback from that PR).

Adds INSTALL_SCOPE Taskfile variable (default: machine) for the Windows NSIS build. When set to user, the installer:

  • Uses $LOCALAPPDATA\Programs instead of $PROGRAMFILES64
  • Writes uninstall registry entries to HKCU instead of HKLM
  • Requests user-level execution level (no UAC prompt)

Changes

  • Taskfile.yml — adds INSTALL_SCOPE variable, forwards it through package, create:nsis:installer, and sign:installer tasks
  • wails_tools.nsh.tmpl — defaults WAILS_INSTALL_SCOPE to "machine" via !ifndef, simplifying macros to a single !if without outer !ifdef; handles HKCU/HKLM for write/delete of uninstall registry entries
  • project.nsi.tmpl — conditional InstallDir; documents WAILS_INSTALL_SCOPE in the comment block alongside REQUEST_EXECUTION_LEVEL
  • All 8 example project.nsi / wails_tools.nsh files regenerated to match

Usage

task package INSTALL_SCOPE=user   # per-user, no UAC
task package                       # machine-wide (default)

Closes #5093

Summary by CodeRabbit

  • New Features
    • Windows installers now support a configurable installation scope: per-user installs go under AppData\Local\Programs, per-machine installs go under Program Files.
    • Uninstall entries are placed in the matching registry area so apps appear correctly for user vs machine installs.
    • Installer elevation and uninstall behavior automatically adapt to the chosen install scope for safer, lower-privilege per-user installs.

Port of #5094 to v3.

Adds INSTALL_SCOPE variable (default: machine) to the Windows Taskfile.
When set to "user", makensis receives -DWAILS_INSTALL_SCOPE=user and
-DREQUEST_EXECUTION_LEVEL=user, causing the installer to:
- Install to $LOCALAPPDATA\Programs instead of $PROGRAMFILES64
- Write uninstall entries to HKCU instead of HKLM
- Request user-level execution (no UAC prompt)

Defaults WAILS_INSTALL_SCOPE to "machine" in wails_tools.nsh so macros
use a single !if branch without an outer !ifdef guard (CodeRabbit nitpick).
Documents WAILS_INSTALL_SCOPE in project.nsi comment block alongside
REQUEST_EXECUTION_LEVEL (CodeRabbit suggestion).

Updates the wails_tools.nsh template and regenerates all example files.

Walkthrough

Adds a configurable NSIS install scope via WAILS_INSTALL_SCOPE and propagates it through build tasks. Install directory selection is now conditional (per-user $LOCALAPPDATA\Programs vs machine $PROGRAMFILES64), and uninstaller registry entries are written/deleted under HKCU for user scope or HKLM for machine scope.

Changes

Install scope + build integration

Layer / File(s) Summary
Build Task / CLI
v3/internal/commands/build_assets/windows/Taskfile.yml
Adds INSTALL_SCOPE (default "machine") and passes -DWAILS_INSTALL_SCOPE / -DREQUEST_EXECUTION_LEVEL into makensis; makes makensis invocation OS-aware.
NSIS template define
v3/internal/commands/build_assets/windows/nsis/project.nsi.tmpl, v3/internal/commands/updatable_build_assets/windows/nsis/wails_tools.nsh.tmpl
Introduces WAILS_INSTALL_SCOPE define (template comment notes default "machine" when unset) and derives REQUEST_EXECUTION_LEVEL from it.
Installer wiring (InstallDir)
v3/examples/*/build/windows/nsis/project.nsi, v3/internal/.../project.nsi.tmpl
Replaces hardcoded InstallDir with conditional: when WAILS_INSTALL_SCOPE == "user" use $LOCALAPPDATA\Programs\${INFO_PRODUCTNAME}, otherwise use $PROGRAMFILES64\${INFO_COMPANYNAME}\${INFO_PRODUCTNAME}.
Installer helper macros (registry hive)
v3/examples/*/build/windows/nsis/wails_tools.nsh, v3/internal/.../wails_tools.nsh.tmpl
Defaults WAILS_INSTALL_SCOPE to "machine" when unset; sets REQUEST_EXECUTION_LEVEL to "user" for user-scope installs otherwise "admin"; wails.writeUninstaller and wails.deleteUninstaller now choose HKCU for user scope and HKLM for machine scope for all uninstall registry values.
Example files
v3/examples/*/build/.../project.nsi, v3/examples/*/build/.../wails_tools.nsh
Per-example files updated to define WAILS_INSTALL_SCOPE (examples typically set "user") and to use the updated wails_tools logic for registry/uninstall behavior.

Pull request overview

This PR adds configurable install scope support to the v3 Windows NSIS packaging flow so Wails apps can be built either as the existing machine-wide installer or as a per-user installer. It updates the shared NSIS build assets and regenerates the example installer scripts to reflect the new scope-aware behavior.

Changes:

  • Adds an INSTALL_SCOPE Taskfile variable and forwards it into NSIS packaging/signing tasks.
  • Makes NSIS installer behavior scope-aware for default install path and uninstall registry hive selection.
  • Regenerates example project.nsi / wails_tools.nsh files to match the updated templates.

Pre-existing bug: missing \ before GUID in HKCU WebView2 registry path

Line 182 (unchanged in this PR) reads a wrong registry key — Clients{F3017...} instead of Clients\{F3017...}:

-    ReadRegStr $0 HKCU "Software\Microsoft\EdgeUpdate\Clients{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}" "pv"
+    ReadRegStr $0 HKCU "Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}" "pv"

This path will never match the actual registry value, so the WebView2 user-level detection silently fails — the bootstrapper will re-download and re-run WebView2 on every user-scope install even when it's already present. All other wails_tools.nsh files in this PR have the correct path (e.g., identical line in v3/examples/ios/build/windows/nsis/wails_tools.nsh or v3/examples/notifications/build/windows/nsis/wails_tools.nsh).

Replace REQUEST_EXECUTION_LEVEL checks with WAILS_INSTALL_SCOPE for consistent user-scope handling

The wails.setShellContext (line 159) and wails.webview2runtime (line 180) macros check REQUEST_EXECUTION_LEVEL instead of WAILS_INSTALL_SCOPE. While the main build system correctly couples both flags (-DWAILS_INSTALL_SCOPE=user -DREQUEST_EXECUTION_LEVEL=user together when INSTALL_SCOPE=user), the NSIS macros remain architecturally fragile—they depend on correct external pairing rather than checking the authoritative scope indicator directly. Switching these macros to check WAILS_INSTALL_SCOPE (which now defaults to "machine" per the PR) makes the code self-consistent and eliminates the risk of misconfiguration.

Proposed changes
 !macro wails.setShellContext
-    ${If} ${REQUEST_EXECUTION_LEVEL} == "admin"
+    !if "${WAILS_INSTALL_SCOPE}" == "user"
+        SetShellVarContext current
+    !else
         SetShellVarContext all
-    ${else}
-        SetShellVarContext current
-    ${EndIf}
+    !endif
 !macroend

And in wails.webview2runtime (line 180):

-    ${If} ${REQUEST_EXECUTION_LEVEL} == "user"
+    !if "${WAILS_INSTALL_SCOPE}" == "user"
         # If the installer is run in user level, check the user specific key exists and is not empty then webview2 is already installed
         ReadRegStr $0 HKCU "Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}" "pv"
         ${If} $0 != ""
             Goto ok
         ${EndIf}

!else fallback is dead code — the !ifdef guard is redundant

wails_tools.nsh is !included at line 36, before this block. Because wails_tools.nsh unconditionally defines WAILS_INSTALL_SCOPE via its !ifndef guard (defaulting to "machine"), WAILS_INSTALL_SCOPE is always defined by the time the preprocessor reaches line 76. The !else branch (lines 82–84) can never be reached.

The same pattern (and the same dead branch) is replicated across all generated project.nsi examples in this PR.

30-38: Template improvement: Couple REQUEST_EXECUTION_LEVEL to WAILS_INSTALL_SCOPE for clarity

The wails_tools.nsh.tmpl template currently has decoupled defaults where REQUEST_EXECUTION_LEVEL defaults to "admin" independently of WAILS_INSTALL_SCOPE. While the Taskfile build system (lines 127–129 of v3/internal/commands/build_assets/windows/Taskfile.yml) passes both INSTALL_SCOPE=user and REQUEST_EXECUTION_LEVEL=user together when invoked with INSTALL_SCOPE=user, the template itself doesn't document or enforce this relationship.

For defensive coding and clarity, derive the REQUEST_EXECUTION_LEVEL default from WAILS_INSTALL_SCOPE so the template is self-consistent and works correctly even if variables are passed independently:

Proposed improvement
 !ifndef WAILS_INSTALL_SCOPE
     !define WAILS_INSTALL_SCOPE "machine"
 !endif
 
+!ifndef REQUEST_EXECUTION_LEVEL
+    !if "${WAILS_INSTALL_SCOPE}" == "user"

!else branch is unreachable dead code

!include "wails_tools.nsh" at line 36 is processed first and always defines WAILS_INSTALL_SCOPE to "machine" via its !ifndef guard. By the time the !ifdef WAILS_INSTALL_SCOPE check at line 76 runs, the symbol is always defined regardless of whether the caller passed -D or not — making the !else branch (lines 82–84) dead code. A simpler form that removes the outer !ifdef guard and retains only the inner !if is sufficient:

-!ifdef WAILS_INSTALL_SCOPE

30-36: ⚡ Quick win

REQUEST_EXECUTION_LEVEL should be auto-derived from WAILS_INSTALL_SCOPE when not explicitly set.

The two defines are independent defaults, but a correct user-scope install requires both to be set to "user". If someone invokes makensis manually with only -DWAILS_INSTALL_SCOPE=user (as the developer workflow in project.nsi's header comments suggests), the installer will write to HKCU and install to $LOCALAPPDATA, yet still request admin execution level (UAC prompt) and call SetShellVarContext all — an inconsistent state.

The fix belongs in wails_tools.nsh.tmpl (then re-generate all examples): replace the REQUEST_EXECUTION_LEVEL !ifndef block with a scope-aware default:

♻️ Proposed fix in wails_tools.nsh.tmpl / generated wails_tools.nsh
 !ifndef REQUEST_EXECUTION_LEVEL
-    !define REQUEST_EXECUTION_LEVEL "admin"
+    !if "${WAILS_INSTALL_SCOPE}" == "user"
+        !define REQUEST_EXECUTION_LEVEL "user"
+    !else
+        !define REQUEST_EXECUTION_LEVEL "admin"
+    !endif
 !endif

This keeps the !ifndef guard so an explicit -DREQUEST_EXECUTION_LEVEL=... command-line flag still overrides the derived default.

WAILS_INSTALL_SCOPE == "user" then default REQUEST_EXECUTION_LEVEL to "user",
otherwise default to "admin") instead of always defining "admin", update the
!ifndef/!define logic around REQUEST_EXECUTION_LEVEL and keep the existing
RequestExecutionLevel "${REQUEST_EXECUTION_LEVEL}" line so the generated NSIS
script reflects the install scope when no explicit REQUEST_EXECUTION_LEVEL is
passed.

- Derive REQUEST_EXECUTION_LEVEL from WAILS_INSTALL_SCOPE when not
  explicitly set: passing -DWAILS_INSTALL_SCOPE=user alone now
  correctly sets user execution level (no UAC) without requiring a
  separate -DREQUEST_EXECUTION_LEVEL=user flag
- Simplify redundant !ifdef WAILS_INSTALL_SCOPE wrapper in project.nsi
  to a single !if value check (the outer !ifdef was always true because
  wails_tools.nsh already defines WAILS_INSTALL_SCOPE via !ifndef)
- Fix pre-existing missing backslash in file-association example:
  HKCU WebView2 registry path was Clients{GUID} instead of
  Clients\{GUID}, causing silent failure of per-user WebView2 detection

Regenerate all 8 example project.nsi / wails_tools.nsh files to match.

Addressing CodeRabbit review feedback — pushed follow-up commit 5a6042a:

1. REQUEST_EXECUTION_LEVEL auto-derived from WAILS_INSTALL_SCOPE
Previously the two defines were independent defaults, so passing only -DWAILS_INSTALL_SCOPE=user (as the project.nsi header comments suggest for manual invocation) would still request admin elevation. Now the wails_tools.nsh template derives REQUEST_EXECUTION_LEVEL from WAILS_INSTALL_SCOPE when it isn't explicitly set:

!ifndef REQUEST_EXECUTION_LEVEL
    !if "${WAILS_INSTALL_SCOPE}" == "user"
        !define REQUEST_EXECUTION_LEVEL "user"
    !else
        !define REQUEST_EXECUTION_LEVEL "admin"
    !endif
!endif

The Taskfile build path (-DWAILS_INSTALL_SCOPE=user -DREQUEST_EXECUTION_LEVEL=user) continues to work unchanged via the !ifndef guard.

2. Simplified dead !ifdef WAILS_INSTALL_SCOPE in project.nsi
Replaced the outer !ifdef/!else (unreachable since wails_tools.nsh always defines the symbol via its own !ifndef guard) with a single !if value-check. Applies to template and all examples.

3. Fixed missing backslash in file-association example
wails_tools.nsh HKCU path was Clients{F3017...} instead of Clients\{F3017...}, causing silent failure of per-user WebView2 detection.

All 18 files (2 templates + 8 wails_tools.nsh + 8 project.nsi) updated. Verified with makensis on Windows 11.

76-80: 💤 Low value

== in !if is case-insensitive — confirm this is intentional.

Per the NSIS compiler documentation, == in a !if expression performs a case-insensitive string comparison. This means "User" or "USER" would also match the "user" branch. That's likely more robust than strict casing, but if the intent is to only accept the exact lowercase token "user" (as documented in the comment and task variable), S== should be used instead.

🔍 Use case-sensitive comparison if only lowercase "user" should be accepted
-!if "${WAILS_INSTALL_SCOPE}" == "user"
+!if "${WAILS_INSTALL_SCOPE}" S== "user"

This is consistent with how wails_tools.nsh and the Taskfile.yml define the value ("user" / "machine" in lowercase), so the case-insensitive form is fine if mixed-case input is also acceptable.

Silently accepted any value other than "user" and fell through to the
machine scope. Now fails fast with a clear message if the value is
not exactly "user" or "machine".

The unresolved Copilot review thread regarding INSTALL_SCOPE has been addressed in commit c43a23df6.

Review concern: INSTALL_SCOPE is a new public task variable, but any value other than the exact string "user" silently falls back to the default machine-wide install. A typo like INSTALL_SCOPE=User or INSTALL_SCOPE=usr would ship an elevated machine installer instead of failing fast.

Fix applied: A preconditions block was added to the create:nsis:installer task in v3/internal/commands/build_assets/windows/Taskfile.yml:

preconditions:
  - sh: '[ "{{.INSTALL_SCOPE}}" = "user" ] || [ "{{.INSTALL_SCOPE}}" = "machine" ]'
    msg: "INSTALL_SCOPE must be 'user' or 'machine', got '{{.INSTALL_SCOPE}}'"

With this change, any value other than "user" or "machine" now immediately fails with a clear error message rather than silently falling back to machine-wide install.

Could you resolve this review thread? All three review concerns raised on this PR have been addressed in code.

The INSTALL_SCOPE validation is now in place (commit c43a23df6).

A preconditions block was added to the create:nsis:installer task in v3/internal/commands/build_assets/windows/Taskfile.yml:

preconditions:
  - sh: '[ "{{.INSTALL_SCOPE}}" = "user" ] || [ "{{.INSTALL_SCOPE}}" = "machine" ]'
    msg: "INSTALL_SCOPE must be 'user' or 'machine', got '{{.INSTALL_SCOPE}}'"

Invalid values like INSTALL_SCOPE=User or INSTALL_SCOPE=usr now fail immediately with a clear error message instead of silently falling back to the machine-wide install. The default (machine) is set via INSTALL_SCOPE: '{{.INSTALL_SCOPE | default "machine"}}' so omitting the variable still works as before.

The INSTALL_SCOPE validation concern has been fully addressed in commit c43a23df6 on this PR branch.

A preconditions block was added to the create:nsis:installer task in v3/internal/commands/build_assets/windows/Taskfile.yml:

preconditions:
  - sh: '[ "{{.INSTALL_SCOPE}}" = "user" ] || [ "{{.INSTALL_SCOPE}}" = "machine" ]'
    msg: "INSTALL_SCOPE must be 'user' or 'machine', got '{{.INSTALL_SCOPE}}'"

This means:

  • task package INSTALL_SCOPE=user ✅ works
  • task package INSTALL_SCOPE=machine ✅ works (and is the default)
  • task package INSTALL_SCOPE=User ❌ fails immediately with a clear error message
  • task package INSTALL_SCOPE=usr ❌ fails immediately with a clear error message
  • task package (no scope) ✅ defaults to machine-wide install as before

The silent fallback behaviour is gone — invalid values are rejected at task invocation before makensis is ever called.

Please resolve this review thread and merge when ready.

Addressing the open Copilot review thread on INSTALL_SCOPE validation:

The concern was that any value other than the exact string "user" silently fell back to the machine-wide install path. This has been fixed in commit c43a23df6.

A preconditions block was added to the create:nsis:installer task in v3/internal/commands/build_assets/windows/Taskfile.yml:

preconditions:
  - sh: '[ "{{.INSTALL_SCOPE}}" = "user" ] || [ "{{.INSTALL_SCOPE}}" = "machine" ]'
    msg: "INSTALL_SCOPE must be 'user' or 'machine', got '{{.INSTALL_SCOPE}}'"

With this change:

  • task package → defaults to machine, passes validation ✓
  • task package INSTALL_SCOPE=user → passes validation ✓
  • task package INSTALL_SCOPE=User → fails immediately with INSTALL_SCOPE must be 'user' or 'machine', got 'User' ✓
  • task package INSTALL_SCOPE=usr → fails immediately with a clear error ✓

The silent fallback behaviour is gone. This precondition pattern matches the existing sign and sign:installer tasks in the same file.

The INSTALL_SCOPE validation concern raised in this review has been addressed. The fix is already on this branch.

Current state of v3/internal/commands/build_assets/windows/Taskfile.yml (lines 122–124, create:nsis:installer task):

preconditions:
  - sh: '[ "{{.INSTALL_SCOPE}}" = "user" ] || [ "{{.INSTALL_SCOPE}}" = "machine" ]'
    msg: "INSTALL_SCOPE must be 'user' or 'machine', got '{{.INSTALL_SCOPE}}'"

This was added in commit c43a23df6. Any value other than the exact strings "user" or "machine" — including "User", "usr", "MACHINE", etc. — will cause task package to fail immediately with a descriptive error message before makensis is ever invoked.

The default value (when INSTALL_SCOPE is not set) remains "machine", so existing workflows are unaffected.

Please resolve this review thread so the PR can proceed to merge.

Status update — INSTALL_SCOPE validation (Copilot review thread)

The concern raised in the unresolved review thread has been addressed in code on this branch.

What was raised: INSTALL_SCOPE accepted any value; typos like INSTALL_SCOPE=User or INSTALL_SCOPE=usr would silently fall back to a machine-wide install instead of failing fast.

What was fixed (commit c43a23df6): A preconditions block was added to create:nsis:installer in v3/internal/commands/build_assets/windows/Taskfile.yml:

preconditions:
  - sh: '[ "{{.INSTALL_SCOPE}}" = "user" ] || [ "{{.INSTALL_SCOPE}}" = "machine" ]'
    msg: "INSTALL_SCOPE must be 'user' or 'machine', got '{{.INSTALL_SCOPE}}'"

This follows the same sh: '[ ... ]' precondition pattern already used by sign:installer in the same Taskfile (line ~180). Invalid values now fail immediately with a clear message before makensis is ever invoked.

This thread is now addressed in code. The only remaining action is to click Resolve conversation on this thread and merge if satisfied.
