USAFRet :
Let's back up a bit.
What OS do you have?
What did you 'purchase'?
From where did you purchase this?
What are you looking for the end state to be?
I have 7, I purchased the official Windows 8 Upgrade deal from Microsoft for 40 dollars when 8 first came out, and I want to use it now. In the past going from Windows 7 to Windows 8, I had to find the Windows 8 (NOT 8.1) upgrade assistant to use my key. However, I can only seem to find the Windows 8.1 Upgrade Assistant now, which doesn't work with my key.
I need to download the Windows 8 Upgrade Assistant
