I have already downloaded that, and I don't know if its still on or not (should be) but when I tried to install it again, if said 'Installation failed. Run setup to finish install' then it said 'GTAIV setup wizard ended prematurely', then it closed. What should I do?

No. You can download it for free here: '?do=embed' frameborder='0' data-embedContent>>

I have been playing GTA and it has been working fine for the last few days - until I installed a siren mod. After I installed it, I tried to run the game (as admin like I always do) and the starting screens worked for a couple of seconds, then it crashed. I tried deleting the siren and starting again, which went a couple of seconds further into the start screen, then it froze. I have done everything on the list of things to do that is shown before you start a topic many times before, so it cannot be that. I ran a diagnostic and it said this: BEGIN *SIGNED* LCPD First Response Issue Report Diagnostics Tool Version: 0.4.3 Operating system: Windows7 HomePremium (6.1.1.0 Build: 7601) Service Pack:Service Pack 1 System RAM (GB): 7.95 CPU cores: 4 NET Framework 4.0 installed: True Visual C++ 2010 Redistributable installed: True GTA IV - Installed: True GTA IV - Install folder: C:Program Files (x86)Rockstar GamesGrand Theft Auto IV GTA IV - Version: GTA IV - Asi loader installed: False GTA IV - Asi loader: GTA IV - Asi loader valid: False GTA IV - C++ ScriptHook installed: False GTA IV - C++ ScriptHook valid: False GTA IV - C++ ScriptHook version: GTA IV - ScriptHookDotNet installed: False GTA IV - ScriptHookDotNet valid: False End of *SIGNED* LCPD First Response Issue Report Digital signature: ijHNA9t2wvIy0248StbHMw== I know that it says I should fix it myself, but I already have an ASI loader and scripthook! I checked the GTA folder and they were still there! I don't know why this has happened. The siren mod was the FedSig SmartSiren by Ofc.Chad. Help would be gratefully appreciated.

Ok I had to download the latest version of OpenIV, and that made it work.

Yes, that has made no difference

I would really like to be able to use modded vehicles in GTAIV, and I am using OpenIV to do so. When I select the vehicles folder in the GTA IV folder, an error message comes up, that says 'OpenIV can not work because important information was obtained from the GTAIV.exe. Please, set correct path to the GTAIV.exe in the OpenIV settings.' I don't know what to do. I don't know where the settings for OpenIV are, and even if doing that would make any difference. I have tried using SparkIV and that does not work. Thanks if you can help.

I ran the game and installer as admin and it worked! Thank you so much!

Sorry for the late reply. I have done everything on the list, and LCPDFR still does not work. Like I said before, the G17 diag tool does not work properly for me. Also the only thing to show that LCPDFR has downloaded in-game is that at the start it says something like 'error in script. Emergency lighting failed!'

My problem is this: I download LCPDFR, but when I run the game and press alt-p to start, nothing happens. At the very start of the game I get and error message in the top-left saying that there was an error in script, something to do with emergency lighting. I have checked all my folders in GTA IV, and everything that should be there is there. I have tried reinstalling it twice, which did not work either time. I tried using an older version, which made no difference either. I tried to use the G17 Media IV Diagnostics Tool, but when I do, it gets halfway through, and then it says 'G17 Media IV Diagnostics has stopped working. A problem has caused the program to stop working. Windows will close the program and notify you if a solution is available.' Help would be much appreciated, as I have been trying to get LCPDFR to work for a number of hours now, and I have been waiting to play for months and I only just got my new PC. Thanks
