When attempting an upgrade from Windows 2008 R2 Standard to Enterprise, I get the error “The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue.” The only item listed under the error is “An error prevented a required compliance check from completing. Cancel the installation and try upgrading again.”
I checked the Event viewers and cannot find any related entries. I am running the installation locally from DVD.
The current Windows 2008 R2 installation is at SP1 and is kept up-to-date with the latest MS Patches. It has SQL Server 2008 R2 SP1 installed as well. Additional memory was added to reach 64 Gb so the move to Enterprise addition would be beneficial.
