I recently upgraded from Accounts Receivable 9.0C to 9.1A. I am running Window 7 professional and Windows Small Business Server 2008. It seemed to install fine, no Adagio error messages came up. However, after it finished installing I received a windows "Program Compatibility Assistant" error saying the "program might not have installed correctly" You could pick to "reinstall using recommended settings" or "this program installed correctly". I picked the "it installed correctly" and it seems to be working fine. I was wondering if this is a common problem or am I doing something wrong.
