So assuming I have one copy of RXP (or Citation X) installed in the FS9_Old folder on the D: + traces of the original installation in the Win Registry and now I want to add them in the FS9 virgin which is on C now in the proper place/folder and all fresh. Or do you think I'll have to uninstall all the add-ons first, which I don't really think is workable.
