Hello,
I am very sorry to read you have had issues during the driver upgrade.
We have a special cleaner to remove all elements of a damaged installation.
Would you please be able to try the steps and let me know if you can reinstall 7.9 M7?

I'll feed this back to our testing team to understand what could have happened.
Kind regards,
