OK---I finally got this solved.
Thanks to all for helping.
Part of the problem was being made worse due to me not doing things right!
When I was being asked to run things in admin mode---I was trying that while logged on in normal mode---which wasnt working. I finally booted in safe mode to do the same and I was able to run the setup.exe. this however only gave me the option to install and not repair--so I skipped that.
I then went back to run the activation using the commands and it still errored out like before on some VBS script.
I took the regedit route and went directly after the mounted devices key--and changed what was assigned to C to something else and the drive letter "g" to "c". Then the reboot took care of that issue.
I was presented with a activation window--where I then entered my key again and everything was fine after that.
Thanks once again to all who gave meaningful insights to try and resolve this.
The only other thing that I noticed now----it boots up much slower.
Any ideas why? I have rebooted 4-5 times already and its about 10-12 seconds longer than usual.
