ASI Driver issue with Windows 11

raul-supernova

Hello
My cameras (ASI 1600MM-Pro and ASI 290mm mini) were working fine until I've tried them this week. It gives a driver error "asicamusb3.sys does not pass the windows driver policy". When I click on learn more it directs me to : https://support.microsoft.com/en-us/windows/the-windows-driver-policy-ecd2a78c-750c-415d-93f2-e37302ce0443 Which esentially highlights drivers not passing the Windows Hardware Compatibility Program.

I've tried reinstalling the latest drivers, restarting the PC several times, disabling windows defender, adding the folder of the drivers to Win Defender exclusion list, etc.

Thanks!

Fixed.

Had to start with the driver signature enforcement mode (shift click + restart, then troubleshooting, advanced, mode 7).

Once back in windows, open admin prompt and type:
bcdedit /set testsigning on
bcdedit /set nointegritychecks on

Now both ZWO devices show as unknown device type, not as imaging devices but at least they work...

raul-supernova After this process, do I need to install the drivers and ASIstudio? Or should I install everything before?

This is a provisional solution, I think that ZWO will be who applied any solution for a thousands people that use W11 with ASI cameras

I also have the same problem with my ASI662MC, I tried everything but it is impossible to make the camera connect to the PC with WIN 11, let's hope they fix it soon.
