I think cpre23.dll is a typo. CRPE32.dll was/is located in \system32 folder and likely not the cause of the problem.
Windows no longer allows users to put dll's in the \system32 folder. And because you are using COM there are issue with those legacy components in Windows 7.
Best to use Process Monitor and look for the errors in there and hack your way through resolving the issues. Not supported in any case so you are on your own.
But believe me, that was/is a typo, no such dll as cpre32. Even if you do copy it into that folder you'll likely have to do the same for all of the CR dll's. There were lots of them put into that folder back then...
Good luck
