Windows 7 GTA IV help??

I tried installing GTA IV both in windows xp x34bit and windows 7 x64 bit.... For Windows xp x34 bit, it worked great without any problems... even while patching the game the game is detectable... But for WINDOWS 7 PRO x64 bit, i got several problems.

Fixed via other ppl's solution

Then a second prob occurs which really piss me off:
When the game social club comes out, i tried to press "play" but an error occured "what what said the game is unavailable" What i did after that is i go open the GTAIV manually which actually works for me to start the game.

Third Prob :
the game lagging every couples of frame
(Dont blame on my PC, i got a decent Card and processor " ATI 5870, X4 955BE")

Forth :
when i wanna install the patch released by the official site, it said that my GTAIV copy is undectable.. :mad: WTF i'm so damn angry rite now....

-- >>> what i did to fix it was " i go copy my patched GTAIV version from my Windows Xp rig then transfer to my windows 7 rig" then i can play it without any lag .....

What is bugging me now is :
MY GAME CANT BE DETECTED if i wanna patch it in my WINDOWS 7 RIG, and the transfering progress is exhausting 13GB man!! Social club cant detect it too unless i go open my GTAIV manually.

I tried exporting my Windows Xp registy and imported it in my Windows 7 rig and it doesnt help too..
Windows Registry Editor Version 5.00


[HKEY_LOCAL_MACHINE\SOFTWARE\Rockstar Games\Grand Theft Auto IV]
"InstallFolder"="E:\\Rockstar Games\\Grand Theft Auto IV"

[HKEY_LOCAL_MACHINE\SOFTWARE\Rockstar Games\Grand Theft Auto IV\1.00.0000]

[HKEY_LOCAL_MACHINE\SOFTWARE\Rockstar Games\Rockstar Games Social Club]
"InstallLang"=" /clone_wait /L1033 /zAUTORUN"
"InstallFolder"="E:\\Rockstar Games\\Rockstar Games Social Club"

[HKEY_LOCAL_MACHINE\SOFTWARE\Rockstar Games\Rockstar Games Social Club\1.00.0000]

Is there problem with my registry??? help please....
The ones with WIndows 7 x64 bit, can check if my reg is there any prob with it...

sounds like you got serious issues there, that steam or retail version...cos I've had zero issues with my retail dvd version

Try reinstalling the program again. If that doesn't work, then you should probably call their support.

It's a known issue with GTA IV on Windows XP x64, since you need xp service pack 3 to run the game. Honestly, GTA IV was poorly made for pc, low fps and compatibility issues.

But it may run, try installing/updating Microsoft .Net Framework 3.5 and get latest windows updates:

Microsoft .Net Framework 3.5

Microsoft .Net Framework 3.5 SP 1
Download details: .NET Framework 3.5 Service pack 1
