Quickstart

1. Install from the PowerShell Gallery

   Install-Module -Name MSIXForcelets -Scope CurrentUser
   Import-Module MSIXForcelets

2. Fetch the tooling (one-time)

   The published module stays lean — the Windows SDK packaging tools and the Package Support Framework binaries are downloaded on demand. Since v1.0.2 a single umbrella cmdlet pulls everything in one go:

   Install-MSIXForceletsAllRequirements   # MSIX tooling + Tim Mangan PSF + Microsoft PSF

   Re-run with -Force to update existing components (or -Confirm:$false for an entirely non-interactive run). The individual updaters are still there if you want to pick one:

   Update-MSIXTooling        # Windows SDK: makeappx, signtool, msixmgr
   Update-MSIXTMPSF          # Tim Mangan Package Support Framework
   Update-MSIXMicrosoftPSF   # Microsoft Package Support Framework

3. Open, fix, repack & sign

   $cert = New-MSIXSelfSigningCert -Subject 'CN=Contoso' -Password 'pw'
   $pkg  = Open-MSIXPackage -MsixFile 'C:\Apps\WinRAR.msix' -Force
   
   # apply a ready-made fix...
   Add-MSIXFixWinRAR -MSIXFolder $pkg.FullName
   
   Close-MSIXPackage -MSIXFolder $pkg.FullName -MSIXFile 'C:\Apps\WinRAR_fixed.msix'
   Set-MSIXSignature -MSIXFile 'C:\Apps\WinRAR_fixed.msix' -PfxCert $cert
