Hi Mike, it is definitely possible to run crystal 8.5 on windows 7 and 8, but I've got no experience with the errors you're seeing. I would guess it's related to AutoBiz if that program also has a custom crystal interface, but that's a shot in the dark.

That said, you will want to review the upcoming changes to Adagio's relationship to Crystal reports with your consultant.

Edit: this assumes you have both components installed.
