GTA won't start since i have installed LCPDFR I ran G17 IV Diagnostics and they came up with 0 errors but it still issued a crash I have attached the Dump from G17 IV Diagnostics to my post if someone could help me I would really appreciate it.

You're Grand Theft Auto IV is way outdated.

 

You need to update to patch 1.0.7.0. for LCPDFR to work.

Ran both the installers 2 times and it won't update

What do you mean by "it won't update"? Are the installers not working or is the game just refusing to update?

 

Make sure you extract the installers before running them and also be sure to run them as an administrator. If the game is refusing to update, make sure your installation paths are correct on the updater and check to see if the GTA IV folder is set to read only or not. 

Euhh, if u run it, you have to close GTA. :P
