I want to take a taste of new mods which are only compatible with Patch 7 and wanted to play Multiplayer. So, I tried to install Patch 7. I remembered that I clicked TitleUpdate.msi to update my game. I clicked it but it hanged up with this kind of output:

I tried to extract it via Universal Extractor but Copy Pasting didn't do much and I am worried that not all files are updated. I reinstalled the game, wanted to try again by shifting GTA 4 to another Directory but no sh*t. As far as I remember, there must a registry field so that the patch updates the game. If anyone is good in Registry Editing, please help:
Windows 7 Home Edition (x86)
Directory (Where GTA 4 is installed): C:\Users\Ram\Desktop\Ram Files\GTA Files\GTA 4 Files\Game\Grand Theft Auto IV
Thanks.

It looks like that the uninstaller didn't remove the registry field of my previous Directory where I installed GTA 4.
