"Not digitally signed" EVen though signed by MS
Harsha
I have driver that was signed MS. (.cat and .sys files are signed, and
successfully installed by using right click and install method). It is a
class upper filter. After installation I see the oemxx.inf and oemxx.cat
file in Windows\INF and Windows\System32\Catroot folder respectivly. I see
this issue on both Vista and WIN7
The problem is that when viewing from the Device Manager, Right-Click on
[Device]->Properties
- [Device] Property Sheet -> Driver TAB. Digital Signer appears to be
the correct Software Publisher Name of my company. This is OK.
- Click on the Driver Details button...
- Driver File Details property sheet shows up. But this time the Digital
Signer field shows up with "Not digitally signed"
I am aware of the similar topics for the same issue that has been posted
already (solutions for Vista and Server 2008)
1. http://support.microsoft.com/kb/954070 <-- Vista
2. http://support.microsoft.com/kb/955557 <-- Windows Server 2008 / Vista
note the Cause in #1 different from #2
Is this error related to the links above?
If it is so, is there any solution for this?

What do you mean by "signed MS"? Do you mean you submitted it to WHQL and
got the Microsoft WHQL signature? If so, you wasted your time and money.
The WHQL signature is never checked for a standalone filter driver
installation. A right-click install does not involve Device Manager, nor
does it use a .CAT file.

No, it's not. If it were signed by WHQL, it would say something like
"Microsoft Windows Hardware Compatibility Publisher".

If you signed the files yourself, I believe this is normal. Unless your
certificate is in one of the trusted stores on your machine, the file will
be seen as unsigned.

Only you can answer that, not us. Does your situation sound like the ones
in the descriptions? (I don't think it does.)

Thanks for the reply.
It is actually submitted it to WHQL and got the Microsoft WHQL signature.
Since we have a CopyInf section in the INF file, when we install using
rightclick->install method, it copies oemxx.inf and oemxx.cat file to the
Windows/INF and Windows/System32/catroot/xxxx folders respectivly.
Viewing from the Device Manager,
Right-Click on [Device]->Properties
- [Device] Property Sheet -> Driver TAB.
Digital Signer appears to be the correct.It shows it as "Microsoft windows".
SInce it is not pointing to individual driver and it is pointing to a driver
stack.
Click on the Driver Details button...
- Driver File Details property sheet shows up. But this time the Digital
Signer field shows up with "Not digitally signed"
We have identified an workaround for this. Once after rightclick->install Go
to catroot/xxxx folder and rename the oemxx.cat file as actual cat file name
and then reboot the machine. Now this time it shows up DIgital signer
properly as "Microsoft Windows Hardware Compatibility Publisher".

Interesting. That was a complete waste of money. With a right-click
install, the presence or absence of a signature makes absolutely no
difference to the installation experience.
