not sure if it's in the registry, but if you still have it on one of you're machines, you can go to the 'about' screen and read it from there... i.e. about visual basic 6.0 ...
When I registered dao350.dll with regsvr32 and tried opening Visual Basic, it gave me an error: "Unexpected error; quitting"<BR><BR>I don't have the original installation disks, so I can't reinstall.
