This is an error that can occur when you create a project (here, to compile a program) and the Manifest had not been declared (e.g., where to find DLL, resources, and such). I have seen this error, say, when running Winword. This error is related to Microsoft Visual Studio 2005 / .NET 2.0.
As you have tried to reinstall your "new program", and as Roxio Creator 2009 is using a newer library (i.e., .NET 3.5) I am wondering what Roxio software you refer to???
You may want to update your Windows system with latest WindowsUpdates and ensure your system is free from any Virus and Mal and Spyware!
Also, cleanup your "%TMP%" directory.
Hope this helps.
