Is it possible to set MSI's Public Properties at install time?

[GarethE (keyoke)]

How can I allow setting a MSI's Public Properties i.e. [PROPERTY=PropertyValue] whilst installing via winget?

with choco I can do something like:

...
$pp = Get-PackageParameters

if (!$pp['REGISTRATIONTOKEN']) {
$pp['REGISTRATIONTOKEN'] = "!INVALID KEY"
Write-Warning "Package needs parameter 'REGISTRATIONTOKEN' to install, that must be provided in params or in prompt."
}
...
silentArgs = "/quiet /qn /norestart REGISTRATIONTOKEN="$($pp['REGISTRATIONTOKEN'])""

and end user can provide via switches during install

choco install wvd-agent -s . -y --params="'/REGISTRATIONTOKEN:[Registration key for WVD Host Pool]'"

Many Thanks!

Have you tried winget install --override?

winget install -? displays the options for the install command.

Thanks this doesn't seem to work... I get the MSI UI displayed instead with the possible options

ok this works, but am expecting silent install but the installer UI is shown

We're dependent on the package supporting a silent install. We're looking at adding a key to the manifest so the correct parameters can be passed in to support silent uninstall if one is available.
