Package Dependencies

Pre-install dependency checks (e.g., "needs .NET 8"). Default detection reads the uninstall registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall and matches DisplayName against namePattern, then compares DisplayVersion ≥ minVersion.

Property	Type	Required	Description
displayName	string	yes	Friendly name shown in the installer UI / log.
namePattern	string	yes	Regex matched against installed apps DisplayName.
minVersion	string	no	Minimum acceptable version.
detectionScript	string	no	Path to a custom PowerShell script (overrides default detection). Receives $.name, $.displayName, $.minVersion, $.optional as args. Must return $true / $false.
install	object	no	If supplied, the missing dependency is installed via WinGet. Only triggers in Full (/qf) and Reduced (/qr) UI modes.

Bypassing dependency check

End users can pass MP_SKIPDEPCHECK=1 on the msiexec command line to bypass all dependency checks. Useful for environments where dependencies are pre-installed by other means.
