Hi all, I installed GTA 4 Complete Edition from Steam. The first time I tried playing after installation it worked flawlessly but has been giving me this error ever since. I have tried uninstalling and reinstalling and I have tried using a different Proton version only to get the same error again. I am on Linux Mint 21.3 Cinnamon with 13th Gen i7-3700K, RTX3080 Ti and 32 GB RAM. I haven’t been able to find any help on Proton DB, hoping somebody here might have some idea. And I apologize if this is no the right place for this post, please let me know where I should post it. Thanks!

    Appears it should work pretty well according to ProtonDB

    https://www.protondb.com/app/12210?device=pc

    You might need to install ProtonUp-QT and grab GE-Proton and set the game compatibility mode to “Proton Experimental GE-Proton”

    There are also suggestions of downgrading the game version to remove the launcher (Im assuming the launcher does the windows version check)

    And this user’s problem/solution sounds identical to yours

    I needed to switch to windows 10 support, while firtst launching it said that windows 7 and 8 was no longer supported.

    To fix: in protontricks select GTA 4, Select default wineprefix, Run winecfg, A window should now pop up, at the bottom In Windows version select Windows 10, select Apply and OK Even if you see Windows 10 already selected reselect it and press OK.

    Then it worked perfect.

      If you’re installing proton ge, you should set compatibility mode to proton ge. Proton experimental is Valve’s experimental version of proton, not GE.

        Not doubting you - I thought experimental referred an additional compat layer you select via Proton UP?

          I believe the experimental option is always there in steam, even if you’ve never used proton up. It just contains experimental features that valve hasn’t put into a regular release yet.

          Nope. Experimental is just one version of proton. The latest one. GE would be a completely separate version you’d need to explicitly select

            Thanks! I will have to look at my steamdeck - I guess I have misconfigured something

              I don’t know about steam deck specifically but I do know that on desktop for many years the UI has had a drop-down with various proton versions, and experimental is one option alongside the others.

                Checked - the steam UI for it is identical. GE-Proton didn’t show up immediately when I originally chose Experimental

                  That’s because GE is a separate version you have to install manually. I’m not sure what you’re saying here, but it’s definitely the case that the “experimental” version is just valve’s latest proton version, entirely separate from earlier major versions and GE. It’s called experimental because it’s the cutting edge version that is less stable because they’re constantly updating it

                    Sorry I am just agreeing with you - when I went to check, I was confirming

                    1. the steamdeck UI compatibility is the same as desktop steam
                    2. When I initially selected proton version after installing GE-Proton, the option wasn’t immediately available. I incorrectly then assumed Proton Experimental was what I wanted. After you corrected me, I went back to the compatibility window, GE-Proton was there as an option separate to Experimental. I just didn’t give it time to appear the first time I set it up.

                    TLDR - You are 100% correct, I was just following up to confirm this plus just to say the UI is the same across Deck + Desktop

      Oh wow, I don’t know hos I missed this post on Proton DB, but thanks for posting it here. It got rid of the error but now I tries to launch the Rockstar Launcher but doesn’t launch either.
