@zpvS9 said in Error installing windows PV drivers 9.0.9137:
I have this error too installing the new PV driver, after uninstalling Citrix driver, reboot, execute XenClean, reboot again, it said that an unsupported device is still present. I must uninstall the device by showing hidden device in Device manager and the Windows PV driver now install. So adding this step in XenClean would be appreciated.
encountered the same problem with hidden base system that i needed manually uninstall to get the tools to work.
