|Sorry but what OS is?|
OS=Operating System-ie. Windows XP, Vista, or 7...But, evidently, Mkey did not look at your screenshot, as it looks like you have XP?
But, when you un-installed the game before, did you revoke the license first?
Anyway, this post from Girish may help(it does for SA, so it might for IV):
|If you're on Vista, you'll need to do this:|
1) Uninstall IV.
2) Delete the installation folder if it still exists. (e.g. C:\Program Files\Rockstar Games\GTA IV).
3) Delete the Virtual Store copy of the installation folder too. The Appdata folder might be hidden.
4) Delete the .set file from your user files folder.
6) Reinstall IV.
Also, where did you obtain the discs? Are you using the ORIGINAL discs to install from?
Also, Please post the REQUIRED information from the Pinned Troubleshooting topic, as posted by Justin(A Moderator):
What is your Processor?
What is the Processor Speed?
What is the Ram?
What is the Video card?
What is the vram?
How much dedicated vram?
What is the Sound card?
What is the OS?
Do you have the latest SP for the OS-ie. SP3 for XP, SP2 for Vista, and SP1 for 7?
Any mods or trainers?
Any Daemon tools or the like installed on PC?-these can cause problems with games.
Is this the Retail(DVD) version OR a Downloaded version?
If Downloaded, from where?
If Retail, Is this the Original DVD OR a Copy of the DVD OR a No-DVD crack?
This will help people fix the problem...Please read and utilize the Pinned topics in the future..Thanks
To find the above information, Go to Start, Run(if Windows XP)/Search(if Vista or 7) and type in DXDIAG and press Enter. The First screen is the Processor and Ram info. then click the Display tab and that is the Video card info. the Sound tab=Sound card info.
|I tried with Deamon tools lite,then comes the same setup.exe thing up.|
Also, Daemon tools may be causing the problems, so it is best to un-install any Daemon tools you have on your PC...
