The WiX build was failing due to several WiX v4 to v6 migration issues.
Workflow changes:
- Uninstall existing WiX before installing v6.0.2 (force clean install)
- WiX version: 4.0.0-preview.0 -> 6.0.2
- Extension: WixToolset.UI.wixext/4.0.0-preview.0 -> WixToolset.UI.wixext/6.0.2
- Fixed extension command syntax: "extension -g add" -> "extension add -g"
installer.wxs changes (WiX v6 migration):
- Added ui namespace: xmlns:ui="http://wixtoolset.org/schemas/v4/wxs/ui"
- Replaced custom inline UI with standard <ui:WixUI Id="WixUI_InstallDir">
(fixes WIX0094 error for WixUIValidatePath custom action)
- Changed Directory to StandardDirectory for DesktopFolder (fixes WIX5437)
