“The RUNE version of Forza Horizon 6 boots to the splash screen, then shows a black screen and crashes to desktop.”

If you’re seeing that kind of launch failure, or messages like “amd_ags_x64.dll is missing,” “could not be located,” or “the code execution cannot proceed because amd_ags_x64.dll…”, the usual cause is a missing, corrupted, blocked, or mismatched game DLL. In one word: the game is failing to load a file it needs to start.

The safest fix is to verify or repair the game files first, then update your GPU driver, run the game as administrator, and check whether antivirus quarantined the file. Avoid random DLL download sites and don’t copy AGS DLLs from unrelated games.

What do these amd_ags_x64.dll error messages mean?

These messages are usually the same problem showing up in different ways:

• “amd_ags_x64.dll is missing”: the game can’t find the file where it expects it.

• “amd_ags_x64.dll could not be located”: same idea, but sometimes caused by a broken install path or deleted file.

• “The code execution cannot proceed because amd_ags_x64.dll…”: Windows found a problem serious enough that the game can’t keep launching.

Why it matters: when this DLL is missing or broken, games may not launch at all.

What is amd_ags_x64.dll in Forza Horizon 6?

In Forza Horizon 6 Wiki, amd_ags_x64.dll refers to the AMD GPU Services Library file used by games for graphics-related initialization and feature handling.

Despite the AMD name, this kind of error is not limited to AMD GPU owners. The game can still throw the error on an Nvidia system if the bundled file is missing, corrupted, blocked, or the install is incomplete.

Common triggers include:

• a bad patch or incomplete update

• corrupted game files

• antivirus quarantine

• accidental deletion

• outdated graphics drivers

• permissions issues

• mismatched DLL versions

Why This Error Happens in Forza Horizon 6

The amd_ags_x64.dll not found error usually happens for one of these reasons:

• The game file is missing or corrupted

The DLL may be missing from the install folder because the download or update did not finish correctly.

• Windows Security or antivirus deleted/quarantined the file

This is very common when the game worked yesterday but fails today.

• The game was moved to another drive incorrectly

If the game folder was copied manually instead of moved through Steam, Xbox App, or the launcher, some runtime files may be missing.

• The wrong DLL was copied into the folde

Downloading a random DLL from the internet can create a version mismatch. AGS files are not always interchangeable between games.

• The game is not an official build

If you are using a repack, cracked version, or modified executable, the DLL may be removed by antivirus or missing from the package. This guide only covers normal troubleshooting for official PC installations.

What should you try first?

Start with the fixes that restore the original game files safely.

1) Verify or repair the game files

If your launcher supports file verification, do this first. It’s the cleanest fix because it replaces missing or damaged files with the correct version for that build.

This is especially important with AGS files, because version mixing can cause crashes and GPU initialization problems.

If your platform has a repair or verify option, run it before doing anything manual.

2) Reinstall the game if verify is unavailable or fails

If file verification doesn’t exist on your launcher, or it finishes and the error still appears, do a clean reinstall.

A reinstall can restore all missing game files, including the correct DLL. If possible:

• uninstall the game

• reboot the PC

• reinstall from the official launcher/source

• let all updates finish before launching

If the install was interrupted, paused, or your connection dropped during download, a reinstall is often more useful than chasing the DLL by hand.

3) Update your graphics driver

Because amd_ags_x64.dll is tied to GPU services, an outdated or broken graphics driver can also trip launch problems.

Update whichever driver you actually use:

• AMD Adrenalin driver for AMD GPUs

• GeForce driver for Nvidia GPUs

• Intel graphics driver if you’re on integrated graphics or hybrid laptop setups

A clean driver install can help if a normal update doesn’t.

4) Run the game as administrator

If the file exists but the game can’t access it properly, this can be a permissions problem.

Try:

• right-click the game EXE or launcher

• choose Run as administrator

• if that works, set it in Properties > Compatibility

This is not the most common fix, but it’s quick and worth testing after verify/reinstall and driver updates.

5) Check antivirus quarantine and the Recycle Bin

Security software can sometimes flag or isolate DLL files, especially right after an update or fresh install.

Check:

• your antivirus quarantine/history

• Windows Security protection history

• the Recycle Bin in case the file was deleted manually by mistake

If you find the file in quarantine, restore it only if you’re sure it came from your legitimate game install.

6) Run System File Checker

This won’t usually replace a game-specific DLL by itself, but it can fix underlying Windows corruption that contributes to launch issues.

Open Command Prompt as administrator and run:

sfc /scannow

Then reboot and test the game again.

Should you manually replace amd_ags_x64.dll?

Only as a last resort.

If you’ve already tried verify/repair, reinstall, driver updates, admin launch, antivirus checks, and SFC, then manual restoration can make sense — but only if the file comes from the exact same game build or another trusted install of the same version.

Safe rule:

• use the file from the same game, same build, same platform source

• or restore it through an official reinstall/repair

Unsafe rule:

• don’t download random DLLs from DLL websites

• don’t copy AGS DLLs from unrelated games

• don’t drop a System32 version into the game folder just because it worked for someone else in a different title

That last one matters. Evidence from other games shows AGS versions can differ by year/build, and mixing them can create new crashes instead of fixing the launch.

What’s outside your control?

If the file keeps disappearing after a clean reinstall, or the same error started right after a game update, the issue may be on the game side rather than your PC side.

That usually means one of these:

• the shipped game build has the wrong file set

• the launcher delivered a bad patch

• the current build has a compatibility bug with certain drivers or setups

At that point, repeatedly downloading random DLLs is usually wasted time.

Linux/Proton: is there a different amd_ags_x64 issue?

Possibly, but this is a niche edge case.

On Linux/Proton, some players reporting black screen or FHE01 behavior have pointed to WINEDLLOVERRIDES settings involving amd_ags_x64. One reported fix specifically said to remove an amd_ags_x64=n,b override on Nvidia.

Treat this as limited community-only troubleshooting, not an official fix. It’s also separate from the normal Windows-style missing DLL error.

I would only try this if:

• you’re actually on Linux/Proton

• your issue is black screen/FHE01 rather than a standard missing DLL popup

• you already know how to safely edit launch options and roll them back
