HCK test on Win7 x64

Hi All,

I’m doing the HCK WHQL test on Win7 x64. It failed with one of my driver as follows:

Driver SaiKa221 can’t be unregistered (0x80041008).

What kind of issue could it be? How should I start to debug it? I’m using the latest HCK studio loading the latest filter. I’ve been running it more than 5 times and the issue still exists consistently.

Also, I can uninstall the driver manually.

Regards,
Marshall
