+ 0 Votes We use 8.5 where I work Slayer_ June 7, 2013 at 12:30pm PST It works completely fine on Win 7 64 bit machines. We did have some issues initially with SQL server 2008 (I think that was the version) but then a service pack for the server fixed it I think. I have had ADO fail because SQL connectivity wasn't installed. You could try that. We use SQL 2000 PE and then just choose to install connectivity to get it working. I don't know if this helps you at all, but I can say it does work on modern OS's.
