No, that won't be necessary. Just follow the tutorial and overwrite any files. 

It didnt work but im going to try to see if putting the hotfix on makes it work

 

Data Execution prevention has stopped Grand Theft Auto from working... It only does this with LCPDFR 1.0 if i have .95 it works fine without any problems.

Okay, try adding launch application to DEP. It may help. 

1.       Close all active programs
2.       Click on Start > Control Panel
3.       Click on System and Security
4.       Now view amount of RAM and Processor
5.       Click on Advanced System Settings > Performance /Settings
6.       Now click on Data Execution Prevention
7.       Check “Turn on DEP for all programs and services except those I select” > Add and find GTAIV.exe and LaunchGTAIV.exe

the launchGTAIV.exe turned off dep but the GTAIV.exe didn't let me turn it off because it is needed to run so now what??

Does it still crash? 

yeah 

 

At this time I think a clean install would be advisable. I'm not really sure what could be wrong. 

so what do need to do for that

 

Just uninstall GTA IV, delete any left over files and install the game again. Apply latest patch. Try it. If it crashes on launch, it's a fault with GTA IV, and not LCPDFR- 

Ok the thing that i dont understand is how .95 works fine with all this stuff but 1.0 makes the DEP stop the game.

You and me both actually, it's really weird. I'm kind of stumped as what do do. 

Good news I got the game to load and everything when i completely uninstalled LCPDFR used the manual install when i took my cars off but then the script says that theirs a error in the log so now i just need to fix that i will show working pic of gta iv files. I also loaded the game from the files and running as admin.

The game and LCPDF is now working all I did after manual install 1.0a i downloaded another manual install 1.0 and re copied the files into the GTA IV directory and now 1.0 works!!
