This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package.
C:\WINDOWS\Installer\1eb8b829.msi

Hi Rob,

The error suggests that the downloaded installer file could be corrupted. This could occur in rare cases when performing the download through the Progress Control Panel

Workaround
The easiest workaround is to go to Your Downloads page, download the Telerik UI for WinUI installer from there, and run it. Please try that and let us know the outcome.

Regards,

Nikola
