I have tried installing Xenko 2.1 and during the installation process I get this error in a popup:
An error occurred while installing version 126.96.36.199. Error code 1 while running install package process [C:\Program Files\Silicon Studio\Xenko\GamePackages\Xenko.188.8.131.52\tools\packageinstall.exe]

I cannot see in that information what the error is. I have been using Xenko 2.0 on this machine for quite a while.
[Edit]I have reinstalled Xenko completely, including deleting the roaming data folder, and am still getting the same error.[/Edit]
