GTAIV FATAL ERROR: Windows Vista: Need to have Service Pack 1 or higher to proceed.

jtm33 · 05-04-2010, 08:27 AM

Getting this error upon launch: GTAIV FATAL ERROR RMN20: Windows Vista: Need to have Service Pack 1 or higher to proceed.

How can I fix this? I have tried verifying cache and reinstalling to no effect. Game was working perfectly fine until a few days ago.

jtm33 · 05-04-2010, 08:41 AM

yeah compatibility mode does work, but I want to know why this just randomly started happening a few days ago. I would like to be able to use steam community in-game and launch it without using compatibility.

But I got windows 7 so I dont know why it doesnt work. But im trying to download service pack 1 for windows 7. So if that doesnt work Steam will hear from me!

Yeah, what gives? I'm running Windows 7, not vista... Why do I get this error? How can I contact steam about this?

Sounds like Steam has got its self stuck in compatabilty mode.

This is how I and others have managed to fix it:

1. Hit start->run->regedit
2. Go to key: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
3. Look for a entry with your path to steam.exe
4. Delete that entry
5. If you dont find it there try HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

You should also be able to launch the game via the gta exe located in steamapps > common > GTAIV without the need to mess with the registry, or the need to have Steam running. Steam will still be stuck in compatibility mode, though.

I am also getting this error. I deleted the registry entry with the path to steam.exe with no resolution. I am also on windows 7

snypes · 09-23-2011, 08:07 PM

id also like to say i have windows 7 (service pack 1) and im getting this error! i just got the game today, please help bros!

Fedoteh · 09-24-2011, 11:02 AM

Bump. I've got the same error today. What is going on? Anyone tried reinstalling Steam?

Fedoteh · 09-24-2011, 11:21 AM

Well, i did the compatibility ♥♥♥♥ and now it works. Today i desinstalled a few games from Steam, and it said me something strange. I don't remember the message, but i ignore it and everything works fine, except this. I put compatibility with Windows 7, and now it works. Maybe later i'd try reinstalling steam.

Had the same problem and I have Windows 7 pro w/SP1 was able to fix here is what I did not sure if this will help but give it a try
1. Open your Grand theft Auto IV EFLC folder this is usually located in C:\Program Files x86\steam\steamapps\common\grandtheft auto iv episodes from liberty city\EFLC folder
2. select the LaunchEFLC.exe dont double click it just select it once then right click it
3. Next select at the bottom Properties
4. Now select the Compatibility tab
5. Next you will probably need to select the unchecked box for compatibility mode then select the drop down box and select window 7 or vista if thats what you have.

Not sure why this happened but this fixed it for me and can run it through steam menu. Hope this helps some of you

Be sure to click the apply button too when you change the compatibility just to be safe

I've been experiencing this problem as well. I tried the following:

5. If you dont find it there try HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

But it didn't work. When I deleted the entry I was given a warning message that I might experience some stability issues. Can anyone tell me if I should be concerned?

I've since tried running Rage and it crashes every time I try to open it, but I suspect that is a different issue...

Bear809 · 12-20-2011, 02:04 PM

I have this issue too, bump!

I've got windows 7 and found an easy fix for this. It turned out steam was running in windows vista compatibility mode. This is how to fix it.

1. Right click your steam shortcut.
2. Click on properties.
3. Choose the compatibility tab.
4. Make sure the compatibility mode box is NOT checked.
5. Restart Steam

Your game should be working now. This happened to me about a month ago I have no idea why. Some update must have messed things up. Hopefully this helps all of you.
