Setup problems . . .

[_Ray]

Well, I wanted to uninstall then install GTA IV so I could go back to the patchless version and install some mods. When I went to Vista's 'Programs and Features' and clicked uninstall, instantly it popped up saying that it may not have uninstalled correctly, and that I should use administrative settings. I did, and it did nothing. It simply would not uninstall it, no catches. I went onto the IV Disc, and when clicking on autorun, it said either back or Launch Social club, so obviously it still thought the game was installed. I deleted the whole 15GB IV Directory, same thing. I then went through and deleted every registry key I could find, and finally it gave me the option to install. I clicked it, and the window disappeared but then came right back up the same thing. Now it wouldn't install it!

I also have EFLC from D2D installed. I've tried disabling all of AVG, and disabling DEP, as well as using compatibility options. I determined that me moving my temp files directory isn't causing it.

I think it may be a Windows Problem as just for kicks I tried uninstalling EFLC and the same EXACT thing happens. Except, I didn't actually delete the directory, so the game still works just fine. I won't do anything!

I'm running Vista SP2 and am totally up to date on all updates and have Windows Live for Games V3.3 and both IV Installations were fully updated.

How to I reinstall the game?

^Wow, sorry, lots of typos there from quick typing . . . Just try to understand the stupid parts . . .

EDIT 2: And when clicking directly on Setup.exe on the disc, it simply just doesn't appear. No errors or anything. It won't even open in Task Manager as a process.

Oh and EFLC and GTA IV are the only programs that won't uninstall. I've tried uninstalling from the disc or from Windows (with the disc in and with it out) and every way it did the same way.
