HiJeffWhiteside . After you add
RegistryWriteVirtualization and FileSystemWriteVirtualization, when you try to install the MSIX package, indeed these capabilities appear.

Capabilities:
"Write registry entries and files that are not cleaned up on uninstall".

However, when you try to install it, you receive the following error "This app package is not supported for installation by App Installer because it uses certain restricted capabilities.".

The xmlns:rescap XML namespace declaration is added in the package manifest.

The only way i got this to install is by running powershell as admin and use add-appxpackage.

Am i missing something?

Hi alexmarin89 ,

Our policy is currently that AppInstaller does not support installing applications with these restricted capabilities as you observed.

Currently, the work around of using the elevated powershell command is a good option.

Thanks!

Just wanted to add a note to this: Prior to 20-04 OS, the PSF Scripting could trigger a cmd file to run outside of the container, but be aware that as of 20-04 these now run inside the container (even if you ask not to). So yeah, as James suggested you've landed on the best option these days.
