@nando4 suggestion: show a menu-like interface (numbered) for each available adapter, then user can type in number for the adapter to patch for
Great work!

Just tested this small script. I deleted NVIDIA drivers with DDU and installed fresh ones 416.16. First one of the cards have got Error 31 (need install drivers), after i installed them i did re-boot and there was Error 43. I run script, answered new questions and re-boot. Error 43 is gone.

Worked perfectly. I tested with EXP GDC 8.4d mPCIe, on the 1030 and 1050 Ti!

Got tired of programs giving me the middle finger when I tried to run on driver 372.70. No newer driver would work, no older driver would work.
Decided to finally update my drivers to 416.16, and this script turned out to be a godsend when I encountered error 43.
