Hi Greg,
That is likely the issue. CR 8.5 is not side by side compatible, we loaded a bunch of dll's into the \windows\system32 folder and have the same name, crpe32.dll is the major one as current versions, and they can cause problems obviously if loaded in the same app.
So I suggest uninstalling CR 8.5, but the problem is the uninstallers did not work very good back then. You may have to manually delete all of the files after using the Add/Remove or Programs and Features to remove CR 8.5 and then look for the left overs.
Unfortunately we don't have a list of what those may be...
