The Inno wrapper deployed per-user content to {userappdata} which resolves to whichever user is running the installer (SYSTEM under DSC, single user under PreInstall) so Azure-AD users never saw the profiles. Setup-OpenText.cmd is a tiny launcher that hands off to Setup-OpenText.ps1 because the runner only handles MSI/EXE types. All bundled files live in vcredist-style subtree at dependencies/opentext/ and get xcopied through WinPE staging. NO DetectionMethod here on purpose - Setup-OpenText.ps1 owns its own version check by reading version.txt next to itself and comparing to HKLM:\\SOFTWARE\\GE\\OpenText\\Installed; the runner always invokes the wrapper (cost: ~1s of PowerShell launch when up-to-date) so the version constant lives in exactly one place: dependencies/opentext/version.txt.",
