Hello everyone...
I also had the issue, on win7 64 bit and office 2010 professional plus 64 bit; none of the access wizards would run. I tried every step folks mentioned in this and other threads: deleting the VB7 folder, deleting the ACCWiz folder, making sure the ACCWiz
folder was trusted, searching the registry for bad references, etc. Nothin worked.
On a whim, I opened the ACCWiz folder, and doubleclicked the ACWZMAIN.ACCDE file, to see what happened. Access opened, and I got a message that the feature was not installed and would I install it now. I responded yes, and let it run, then closed Access
and then reopened it and was able to run the import wizards successfully.
