A digitally signed driver is required on Windows 8.1

Question

I need some help with a hello world KMDF device driver which I followed as per the web page. I compiled and built the device driver but when I try installing the driver I get the following error message. How can I install this very basic and simple device driver without needing it digitally signed ? Thanks

Answer 2

[Update] I tried the above suggestions (and rebooting) after disabling Secure Boot from the BIOS but I still get the same error message. Anyone have any other ideas ? Could it be the driver installer application which I am using ?

Answer 3

Well I think the two commands worked because in the command window it shows that they executed successfully. After the reboot as per the instructions we have the following output at the lower right of the home screen. But when I try loading the simple Hello World KMDF driver the above error message appears and the driver does not load.

Problem solved just disabled the Program Compatibility Assistant service.
