- Use SetProperty + WixQuietExec two-step pattern to pass runtime
INSTALLDIR to a deferred CustomAction (fixes WIX1077 and WIX0400)
- Add WixToolset.Util.wixext/7.0.0 extension (required for WixQuietExec)
- Fix condition syntax: collapse multi-line conditions to single line
- Add -ext WixToolset.Util.wixext to wix build command in windows-msi.yml
**`build-aux/windows/QElectroTech.wxs`**
- Desktop and Start Menu shortcuts now point directly to `bin\qelectrotech.exe` with all required arguments (`--common-elements-dir`, `--common-tbt-dir`, `--lang-dir`, `-style windowsvista`) — no `.bat` wrapper needed
- Added a deferred `CustomAction` that runs after `InstallFiles` and recursively sets all files in `elements\` to read-only using an inline PowerShell command
**`.github/workflows/windows-msi.yml`**
- Replaced the step that created `Lancer QET.bat` with a step that removes it from the artifact before the WiX build, so it is not embedded in the MSI
- The `.bat` file remains untouched in the ZIP portable build (managed by `windows-build.yml`)
- No console window flashing when launching QElectroTech from the MSI shortcuts
- The `elements\` directory is properly set to read-only after installation, as required
- Cleaner MSI package — no `.bat` file shipped to end users installing via MSI

windows-msi.yml
├── uploads the portable artefact
├── builds the MSI with WiX v7
├── deletes the old .msi, uploads the MSI to the nightly version
└── generates and deploys GitHub Pages ← the 3 URLs are known here
The GitHub Pages page is no longer generated by windows-build.yml but by windows-msi.yml once the MSI is in the release
Removal of all envs: WIX_ACCEPT_EULA: true (does not work)
Addition of a dedicated ‘Accept WiX EULA’ step with wix eula accept wix7 before any other WiX command — this is the official CI/CD method, which writes a sentinel file to the user profile, thereby authorising all subsequent WiX commands in the same job.
