To complete a case study for my Accounting Information Systems class, we had to install a small software. The case study was completed, corrected and I graduated. I now wish to uninstall the software but I get the following message : Incorrect target operating system. During the 1st attempt to install the software I received this same message. But, my 2nd attempt to install was successful. I imagine I could always manually delete the appropriate directories; but, how do I effectively clean-up the registry and any stray files? Many thanks. PS: I love the new set and format. I do miss the old gang but am getting to know the new people. I appreciate the variety of subjects as well as the expertise and enthusiasm of all who make the show.
