You must remove everything and then reinstall everything. But this time install MO2 and MO3 into separate folders.Install RA2 YR first. Create a copy of it. I think it is the best to create 3 RA2 YR folders, one for MO2, one for MO3 and one for backup. Reinstalling RA2 YR alone won't work, because the interference persists.
You don't understand what i'm trying to tell you about reinstalling these things.
First:MO3 doesnt even register as installed by the windows.It just goes through the installating without errors yet the folder doesn't have any new files in it nor does it say in "programs and features" that i have installed it so that i can unistall it.
Second:MO2 doesn't even want to install regardless if i reinstall RA2 and RA2:YR or if i backup it 5 times(which i did sadly).It just says YR not found and it doesn't have the option of me personally selecting the folder.
