This is mainly for information to anyone who might run into what I just did:

I just installed Word Perfect Office X6 to my windows 8 computer, and when I attempted to open Quatro Pro and/or Word Perfect, I got a runtime error.

I didn't find anything on the error here in the forums, so I went to Corel. Of course, Service Pack 1 and 2 were available for download as was a Hot Patch. After applying the service packs and the hot patch, I no longer get the runtime errors.

As I said, just for information . . .
