Package creation stopped due to Drivers failing Signability tests.

Hello, NTDEV!
Now I’m working on signing driver for Win7 using HCK tests. So I passed all tests and in the end (package tab), when I wanted to create package I got an error “Package creation stopped due to Drivers failing Signability tests.”. Can someone please explain me what I’m doing wrong.

Are you able to run inf2cat on your own driver? I believe that runs the same signability tests.
