If gtaencoder.exe is running at the time you will not be able to remove it or replace it. Do a fresh reboot to make sure nothing is running before trying to uninstall/install.

 

What do you mean by downgrade?

The game must be launched through RGSC "PLAY" button, and you must use the original "LaunchGTAIV.exe" that came with the game.  If these conditions are not met you will see the EFC20 Error.

OK but.. in a Momo Steering wheel support post (on this forum) one of the Rockstar employee said to target GTAIV.exe and create a profile targetting this exe and launch it from the profiler,but when i do,it crash with the EFC20 error?!

 

 

 

here is the thread about it

http://www.gtaforums.com/index.php?showtopic=394430

You should be able to target the exe, then run the game through RGSC. Once the game is loaded, go into the Controller Options menu and enable direct input devices.

I'm a little bit confused, I remembered that the previous patches delt with the "Fatal error" problem. With the 3rd patch the problem seems to reappear. Sigh...

Can you read?

yeah last time I checked, but perhaps I should pose the question to you...

 

I didn't have to start the game from the RGSC "PLAY" button so why should I start now. For your information, I have tried starting the game through RGSC but I still get the same error message. The patch is meant to fix problems not cause them or have I missed something?

 

Do me a favor, please follow the discussion before making any stupid comments!

The game has always required you to run by pressing "PLAY" in RGSC. If you had another way to launch the game that is probably what is causing your issue now. Can you tell us how you were launching before if not through RGSC?

I've simply allowed RGSC to automatically startup every time I log on to windows. I simply run the game through the original "LaunchGTAIV.exe". I have tried starting the game through RGSC but I still get the same error message.

 

I downgraded to patch 2 and it works just fine...

Maybe your feeling isn't so far from the truth. I'm still trying to figure out how I can play Crysis, smoothly and on DECENT graphics but can't even get this game to work without lag (all settings on low).

 

Try applying the 2nd patch for now and settle with that one until we get to the bottom of this.

Simply download the 2nd patch, if you don't already have it on your computer and run it.

Perhaps I´m totally dumb, but the "Memstricts" proposed I used to place in the .exe file back in january...

 

But now we get the info from R*, that altering in this will cause the below mentioned error which I´m also getting now:

 

EFC20 - Invalid resource detected - Please re-install the game

 

 

SO how I´m I supposed to implement a menstrict now?

Please don´t flame poor me...

I'm not sure how you were launching the game before, but the method for using commandlines is unchanged.

 

The easiest way to do it is to create a .txt file in notepad called "commandline"

 

Inside the txt file you can add "-memrestrict XXXXXXX" and when you press the "PLAY" button in RGSC it will read this file.

 

You cannot launch the game with GTAIV.exe without getting an EFC20.

 

You can Launch it with "LaunchGTAIV.exe" but ONLY if you are signed into RGSC.

Check to make sure you have the latest GFWL redistributable installed.

Have you always launched the game with RGSC? Are you able to sign into RGSC?

So, we have one person from UK, one from USA, and one from Ukraine with same problem...that means the problem is not about the version of the game...mercie_blink.gifsuicidal.gifsad.gif

Make sure to use the original LaunchGTAIV.exe and GTAIV.exe and make sure your using the unmodified version of the game. If the problem is persistent downgrade to version 1.0.2.0.
