Signed driver when started gives, error 577

Question

When I start the driver I have written on Windows Server 2008 x64, it gives Error 577.

Windows XP 32-bit works fine, but Windows XP 32-bit doesn't have driver signing restrictions.

Don't know if there's an issue with my .inf? What could be wrong here?

Answer 1

If you are using a Test-Signed Certificate during you development you need to allow the machine, on which you install your driver, to use a test certificate

To do it

Open Command Prompt (Run as Administrator) Bcdedit.exe -set TESTSIGNING ON Reboot your machine To disable it Bcdedit.exe -set TESTSIGNING OFF and reboot your machine

Answer 2

577 means your driver's signature is incorrect,

How did you sign it? Besides, did you sign it for development and test or for production?

You should strictly follow Microsoft's articles so as to avoid any problem like this,

Answer 3

That can happen when a driver is properly signed. The specific problem occurs in Windows 7.
