I'm trying to use the RBC9 SpaceNavigator TEST x64 build drivers for my SpaceNavigator 3d joystick so that it can work as a normal joystick in games like Quake. Unfortunately, I get the error "This version of windows requires all drivers to have a valid digital signature" and in the "Device status" in device manager, I get "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)". Is there a way to work around this issue?
