.NET 2.0 Runtime error
.NET 3.5 and 3.0 both use the 2.0 CLR with add-on classes
The main issue, and the issue that causes the mysterious behavior is the unhandled exception coming out of the .NET runtime.
Could also be a MS Office 2007 Font issue
Description of the 2007 Office hotfix package
Download the full package, rather than the bootstrapper.
IMPORTANT: After installing the .NET Framework 3.5 SP1 full package you should immediately install the update KB959209 to address a set of known application compatibility issues.
In addition, on Windows Vista/WIN7 x64 and Windows Server 2008 x64, install the update KB967190 to address a file association issue for XPS documents.
