Office 2013, huh? No problem with that.
VARA has been written in a number of programming languages, including Visual Basic, VB is great at accessing Windows resouces like files and devices, while other, more low-level languages are faster and more powerful in calulation and signal processing.
I know that microsoft's Dot.NET framework grew out of Visual Basic, which relied on .DLLs to provide specialized functions.
I'd suspect that you have an older machine, and current VARA is trying to use an older Office 2013 DLL which wasn't required when you installed it.
Perhaps try installing the current dot net framework from Reboot just in case.
Hope this helps, 73,
