After hearing Solstheim will be the next expansion for Skyrim, I decided to take another look at it in Morrowind. So i installed Morrowind, both expansions, and patched. Then I downloaded the Overhaul 3.0 and it won't install. I reach a screen where it attempts to detect my Morrowind installation and it shows Morrowind, Tribunal, and Bloodmoon as missing. My OS is Windows 7 64 Home Premium. How do I fix this so the mod will install properly?

Did you install Morrowind in Program Files (x86)?

I was given no other choice. How would I go about installing it somewhere else if that's the issue?
