Update:
When I was upgrading from the Beta to the final release on Windows 7 Enterprise 64bit, the instalation hanged with Returning IDCANCEL. INSTALLMESSAGE_WARNING [Warning 1946.Property 'System.AppUserModel.ExcludeFromShowInNewInstall' for shortcut 'Manage Help Settings - ENU.lnk' could not be set.]. Canceling the installation didn’t work and I had to kill the setup.exe process.
When reapplying it again, rollbacks were reported, so I reapplied it again – this time with succes.
