My problem is solved…… I unstalled the SST Software and the drivers. Very good cleaning of the pc (and by regedit). I followed the instructions of Gunshow at https://forums.frontier.co.uk/showthread.php?t=153006, thread #9.
Unplug X52Pro device from the computer and I installed first the drivers and after a reboot the software.
The software and the drivers i’ve got from ftp://ftp.saitek.com/pub/software/beta/Windows10/. It’s for Windows 10 but it worked for me with Windows 7 64bits. Now I’ve got my radar cursor by ministick. I hope it helps others too.
I used:
Saitek_X52_Flight_Controller_7_0_42_12_x64_Software.exe &
Saitek_X52_Flight_Controller_7_0_42_12_x64_Drivers.exe.
By the way, I use Flounder’s X52 Pro Keyfile-DX Profile for BMS 4.33. Thanks Agave_Blue.
