I downloaded the latest free version 3.8.1002 and this time decided not to simply overinstall, but to first uninstall the previous version via Add/Remove programs (Windows Control Panel). A/R Progs. went through the motions (as it usually does), and the SAS entry was no longer shown. However, on checking in C:\Program Files it was all still there, and was fully functional ! Trying to delete the folder in C:\Program Files was a no can do situation. Why ? (System hooks ?) Anyway I installed the downloaded new version 'over' what was there, and all's fine. See screenshot. I like SAS and will probably upgrade to Pro. In the meantime, is there a recommended way to uninstall before installing a new version ? What about folks that want to completely uninstall ? .. Regcleaners ? Regards.
