Task at hand: Microsoft sign drivers on Win 7.

I microsoft signed my driver package 3 times every time thinking I might have missed a step or something. However, I cannot seem to get rid of the Windows Security error message "Windows can't verify the publisher of this driver software'. This is not the first time I have signed the driver packages. I was successfully able to sign other driver packages a few months ago. However, with this driver package I keep getting Windows security dialog box. Here's the procedure I follow -

1. Create a new cat file using INF2CAT tool.

2. Self sign the driver using a Versign Class 3 Public Primary Certification Authority - G5.cer.

3. Run the microsoft tests on DTM Servers and clients with the devices that use this driver.

4. Create WLK submission package.

5. Self sign the cab file.

6. Submit the package for certification.

The catalog file that comes back after successfully passing tests says Name of signer "Microsoft Windows Hardware Comptibility Publisher". When I check the validity of signature using SignTool, it says the signature is vaild. However, when I try to install the driver with new signed catalog file the windows complain.

Any ideas?

Thanks for the help, Eugene. Yes. I did sign two other driver packages before. One of them was modified version of WinUSB driver. I am using the same certificate I used when I signed those two driver packages a few months ago. It costs $250 per signing from Microsoft. I would think that Microsoft would complain about it during certification if the certificate is wrong. I use the following command to self sign the CAT file. I don't have to specify the ceritificate name as there's only one certificate in the directory -

Signtool sign /v /a /n CompanyName /t http://timestamp.verisign.com/scripts/timestamp.dll OurCatalogFile.cat

Below is the result from running Verify command on the Microsoft signed OurCatalogFile.cat

C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\x64>signtool verify /v "C:\User s\logotest\Documents\serialdriversigning\OurCatalogFile.cat"
