You will likely have to use RegEdit to remove all the HID devices and anything related to Pronto after uninstalling all releases of PEP. Not sure if there is anything here on this site discussing this. Might search for regedit in the Pro forum to see if there are any hits. I know I put up a thread in the NG forum that was with regard to the TSU7000 driver reinstall. Looking at that thread might give you some good hints on what to look for in RegEdit.


Please also note that there is an installer that lingers around that you will also have to remove via the registry. It is a fake item called ‘support’ or something like that. Have a look at Programs and Features and you will likely find it.
