Dear Cuffy, I welcome your help.
OK, I'll see what I can dig up.
In the words of Dr. Verner von Braun, the rocket scientist, "before we can get where where we ain't, we gotta know where we IS!
I downloaded the media and burned an ISO to install the original offering of Win8.0.
Recapping from memory here, that offering for $40 bucks was an upgrade version. I had a copy of Win7Pro 64 on the machine that I wanted to install Win8.0Pro 64 onto and I didn't want to lose that copy of Win7.
I pulled the drive, installed a spare, installed a copy of WinXP 64 on that and downloaded the Win8 ISO media, along with the free key to install Windows Media Center.
With the new ISO I upgraded WinXP to Win8.0 and activated it.
I then installed Windows Media Center through the Windows Features thingy and using my free WMC key I activated that.
The WMC key changed the Win8.0 key and that DE-activated my Win8.0 install.
The deactivation problem was wide spread and a big fiasco. In the process of trying to get all the keys straightened out the update to Win8.1 was offered at the Windows Store and installing that trashed my install of Win8.0 /WMC.
Eventually Nirsoft's Produkey plucked my keys out of that trashed install so I again had valid keys to work with.
Now the ISOs to start over came into the picture so let me start there and see if I can determine where I got the media and we can go from there if we are still on the same page.
What media do you have and are you prepared to download what you need (if I can find the source that I used)?
talk to me while I look through my miscellaneous file of a TB or so....
