Run the included automatic setup tool (SetupSpad.exe). Before using SPAD you must uninstall all previous installed Saitek drivers.
SPAD is not compatible with UAC (User Account Control).
If you want to run SPAD on Windows Vista or Seven you have to either disable UAC or run SPAD with Administrator rights (right click and select “Run as Administrator”).
OR: right click on the spad.exe file and select Troubleshoot compatibility. Let it run as Vista SP2. You can check the properties of the file > Compatibility tab
