Changing the dword to 00000000 solved the problem.
This worked perfectly for me. Thanks so much!
This fix works. I had a similar problem, same error message, but happened upon startup.
Even though it's an Autodesk registry, I blame Microsoft.
For those of you not computer savvy out there, to edit your registry keys, go to:
Start-->Run-->type in 'regedit'-->Navigate to folder location. Then edit as necessary.
Sometimes a reboot may be required.
-Those who don't know, run Windows. For everybody else, there's Linux.
