Cannot Launch Backup Exec after upgrade to 2010

We just upgraded our backup exec from 12.5 to 2010. Now, when we attempt to launch Backup Exec, it gives us the following error: "Could not load file or assembly 'presentationFramework, version 3.0.0, culture=neutral, publickey=31bf3856ad364e35 or one of its dependencies. The module was expected to contain an assembly manifest."

I already tried installing .net framework 4 since it seems like .netframework might be broken but that didn't seem to work. Any help on this would be greatly appreciated.
