Forum:I uninstall GTA IV and now I cannot reinstall it

Hi, I'm sorry for my bad english, I'm italian.

I bought GTA IV and I installed and activated it. When I started to play it asked me the connection to Rockstar Game Club, so I decided to uninstall it and reinstall without Window Game Live and Rock star club...

The uninstall give me an error of securom. I've tried to remove the activation, I've tried to remove securom, I've tried everithings. Now the setup seems to find the application, but the file in the hard disk are lost and if I try to run it the LaunchGTAIV.exe are missing.

So, I cannot install and I cannot uninstall!!!! How can I do? I have writed to securom support but they say me:

"It appears, according to the screenshots, that the application has been uninstalled, however the cleanup of some files did not complete. You will need to contact the software publisher, Rockstar Games, in regards to this error".

Please can sombody help me?

Best regard
