For those who run a G27 wheel and got the automatic download from 2016, here is the fix which allows the profiler recognise your G27 wheel and return to normal.
Uninstall the G27 and profiler before completing these steps.
1. Launch lgs510_x64.exe from Logitech drivers.
2. Don't click anything in the driver pop-up but just leave it opened
3. Open C:\Users\YourUserName\AppData\Local\Temp\
4. Do a research with CTRL+F and search for the folder 2b-LGS-x64
5. Open the most recent folder named 2b-LGS-x64 and go to \Common64\Logitech\WMDrivers\
6. Right-click on wmjoyhid.inf and Install. Don't accept the reboot. Close all windows.
7. Close also the driver pop-up and launch again lgs510_x64.exe. Click on next and so on, as usually. This time, the wizard should recognize your G27 as a G27 wheel Smiley Happy
8. After installing, reboot your PC.
And wallah!!
