I have a major problem getting my sandboxie driver working under windows 7.
I ran the HCK tests and the HLK tests as required to get a signature from MSFT and in this hardware partner center web thingy it sees that it should work in w7 and w10 and returns a signed driver.
That driver also works just fine under windows 10 but for some reason windows 7 still complains about the signature.
I have the sha265 update for w7 installed so that's not it.
Any idea what I may be doing wrong?
I know one way of signing would be to sign the driver with a certificate that w7 accepts directly before submission and get from MSFT only the signature for w10 but as this will no longer work past April 2021 that's not a solution, see: https://docs.microsoft.com/en-us/windows-hardware/drivers/install/deprecation-of-software-publisher-certificates-and-commercial-release-certificates
So I wanted to go the WHQL route and get a w10 and w7 signature from MSFT, and seemingly they are not complaining at any step of the process.
Just that in the end it does not work for w7, why?!
I already spent a week trying to get this to work but to no avail, so I wanted to inquire here if anyone has any experience with the new way of getting drivers signed to work on w7 and w10?
