I didn't use the disc supplied with the 6022be. Regardless of anything I buy or what computer I'm using I always download drivers to ensure I have the latest driver version. In this cause though, I downloaded the driver because I don't have an optical drive in my computer. I also already tried going to the device manager, uninstalling the driver, unplug the 6022be, plug the 6022be back in and it auto installed the driver. Still the same issue. So I tried going to device manager, uninstall the driver, unplug the 6022be, open programs & features to uninstall the hantek software, reinstall the software, plug the 6022be back in. Still the same issue. I also clicked on update driver, clicked browse for drivers, navigated to the hantek download and clicked ok to update. It said the driver was updated. Still the same problem. That's when I started thinking there was a problem with my 6022be. I took it to my girl friends computer, installed the software, plugged in the 6022be.....everything works fine. I could have sworn I saw someone was having a similar issue and someone typed or linked instructions on how to uninstall the 6022be drivers to fully clean them out and start new but I can't find it now. Perhaps I was dreaming about seeing that. I am running Win7 Ultimate 64bit.
Sorry for the misunderstanding with your post on uninstalling the drivers.
