How to Fix Gunman Contracts Stand Alone OpenXR Runtime Error

Gunman Contracts – Stand Alone has the kind of VR gunplay that makes you forget you’re standing in front of a PC. It wants to feel like a gritty action movie where every room is a problem and every contract can turn into a mess. That’s exactly why an OpenXR Runtime Error is so annoying. You have the headset ready, Steam is running, the game is installed, and then Windows throws a cryptic message at you instead of letting you play.

Errors such as “OpenXR Runtime Not Found,” “Failed to initialize subsystem OpenXR Display,” or “Could not create openxr system” generally point toward the same basic problem: the game cannot establish a working OpenXR runtime. In other words, Gunman Contracts knows it needs VR, but your PC isn’t successfully telling it which software should handle the connection between the game and your headset.

I’ve always found VR troubleshooting more frustrating than normal PC troubleshooting because there are simply more layers involved. You’ve got Windows, the headset software, SteamVR or another runtime, streaming software, USB or wireless connections, and finally the game itself. One bad setting somewhere in that chain can be enough to stop everything.

The good news is that the Gunman Contracts Stand Alone OpenXR error is usually fixable without reinstalling the entire game. Before you start deleting folders or messing with obscure Windows settings, work through the fixes below in order.

Why Does Gunman Contracts Stand Alone Show an OpenXR Runtime Error?

OpenXR is designed to give VR developers a common standard instead of forcing them to create completely separate implementations for every headset ecosystem. That’s great for developers and players when everything is configured correctly. The downside is that several VR applications can potentially compete to become the active runtime.

Gunman Contracts – Stand Alone needs Windows to point it toward a valid OpenXR runtime. If that runtime is missing, incorrectly registered, broken, or being overridden by another VR application, the game may fail before you even reach the main menu.

The most common causes include:

• No active OpenXR runtime: The headset software or SteamVR isn’t currently registered as the active runtime.
• Runtime conflicts: SteamVR, Meta Quest Link, Virtual Desktop and other VR software may be configured differently.
• Incorrect registry information: Windows may contain an outdated ActiveRuntime path.
• API layer conflicts: VR utilities can interfere with the OpenXR initialization process.
• Incorrect launch sequence: The headset or streaming connection may not be ready when the game starts.

That last point sounds almost ridiculous until you’ve spent enough time troubleshooting VR. Sometimes the difference between a working session and an error message really is which application you launched first.

Quick Diagnosis: What Should You Check First?

Fix #1: Set the Correct OpenXR Runtime

This is where I’d start. Don’t touch the Windows Registry unless you actually need to. Most OpenXR problems are much less dramatic than they look, and the runtime setting is the first thing worth checking.

Meta Quest Link

If you’re using a Meta Quest headset through a Link cable or Air Link, open the Meta Quest desktop application on your PC.

1. Connect your Quest headset to the computer.
2. Open the Meta Quest PC application.
3. Go to Settings.
4. Open the General section.
5. Find the OpenXR runtime option.
6. Choose the option to make Meta Quest Link the active OpenXR runtime.

If the option is unavailable or the setting doesn’t seem to stick, completely close the Meta Quest application and restart it. Also make sure the headset connection itself is active before launching the game.

SteamVR

For a Valve Index, HTC Vive, or a setup that relies heavily on SteamVR, check SteamVR’s OpenXR configuration instead.

1. Start SteamVR.
2. Open the SteamVR menu.
3. Enter Settings.
4. Enable the advanced settings view if necessary.
5. Find the OpenXR section.
6. Check the current OpenXR runtime.
7. If necessary, select Set SteamVR as OpenXR Runtime.

If SteamVR is supposed to handle your VR session, this is one of the most important settings to verify. A blank runtime or an unexpected runtime provider is a major red flag.

Virtual Desktop

Virtual Desktop adds another layer because you can use either SteamVR or the VDXR runtime, depending on your setup.

If you’re deliberately using VDXR, make sure VDXR is selected and launch the game through the Virtual Desktop environment when appropriate. If you’re using SteamVR, keep the configuration consistent and avoid switching between runtimes randomly during troubleshooting.

My advice: pick one runtime, test it properly, and only move to another option if you have a reason. VR troubleshooting gets messy very quickly when several runtimes are being changed at the same time.

Fix #2: Check the Windows OpenXR Registry Entry

If the official VR applications refuse to set the runtime correctly, the Windows Registry is the next place I’d investigate. This sounds intimidating, but the actual check is fairly straightforward. Still, the Registry is not something to experiment with casually. Change only the value you’re sure needs changing.

First, close SteamVR, Meta Quest Link, Virtual Desktop and the game. Disconnect your headset as well.

1. Press Windows + R.
2. Type regedit and press Enter.
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1.
4. Find the ActiveRuntime string value.
5. Check the path stored inside it.

The important thing isn’t blindly copying a path from somebody else’s PC. The path needs to point to the OpenXR runtime actually installed on your system.

For example, a Meta Quest installation may use an Oculus OpenXR JSON file, while SteamVR will use its own SteamXR configuration. Virtual Desktop can also have its own VDXR runtime path.

If ActiveRuntime points toward an old drive, a deleted installation or a folder that no longer exists, that would explain why Gunman Contracts cannot initialize OpenXR.

Be careful here: if you aren’t comfortable editing the Registry, don’t start changing random values. It’s better to repair the runtime through the official VR software or reinstall the affected VR component than to turn one problem into three.

Fix #3: Disable Problematic OpenXR API Layers

This is the fix that tends to matter most to experienced VR users who have accumulated a pile of utilities over the years.

OpenXR API layers can add features, overlays, performance tools and other functionality between the application and runtime. That’s useful, but every additional layer creates another opportunity for something to break.

If you use tools such as the OpenXR Toolkit or other VR overlays and utilities, temporarily disable them and test Gunman Contracts again.

The goal here isn’t to uninstall everything immediately. It’s simply to establish whether the base OpenXR stack works without third-party interference.

• Disable unnecessary OpenXR API layers.
• Close VR overlays and performance injectors.
• Restart SteamVR or your headset software.
• Launch Gunman Contracts again.

If the game suddenly starts working, you’ve found the general area of the problem. Re-enable your utilities one at a time until you identify the conflicting layer.

Fix #4: Start Your VR Hardware in the Right Order

This sounds like basic advice, but VR software doesn’t always behave like a normal PC game. I’ve had plenty of sessions where everything was technically installed correctly and the problem disappeared simply because the headset was connected before launching the game.

For Gunman Contracts – Stand Alone, I’d use this order:

1. Boot Windows and wait until the desktop is fully loaded.
2. Turn on your VR headset.
3. Establish the Link, Air Link, Steam Link or Virtual Desktop connection.
4. Start the appropriate PC VR software.
5. Launch SteamVR if your setup requires it.
6. Wait until the headset and controllers are detected correctly.
7. Only then launch Gunman Contracts – Stand Alone.

Don’t launch the game first and hope the VR software catches up afterward. Sometimes it works. Sometimes it doesn’t. When you’re troubleshooting an OpenXR error, there’s no reason to give the game another variable to deal with.

Still Getting the Error? Try These PC Fixes

Verify the Game Files

Open Steam, find Gunman Contracts – Stand Alone in your library, open its properties and use the Verify integrity of game files option.

A damaged or missing file isn’t necessarily the cause of an OpenXR error, but verification is quick and eliminates one possible source of the problem.

Update Your GPU Drivers

VR puts considerable pressure on the graphics stack. If your NVIDIA or AMD drivers are outdated, update them before spending hours digging through configuration files.

If you recently changed GPU brands, a proper driver cleanup can also be worth considering. Old driver components occasionally cause strange behavior that isn’t obvious from the error message.

Temporarily Check Security Software

Antivirus software and security tools can occasionally interfere with VR applications, overlays or runtime components. If everything else looks correct, check whether your security software is blocking part of the game or VR runtime.

I wouldn’t recommend permanently disabling security protections. Instead, use a temporary test to determine whether the security software is actually involved, then configure an appropriate exception if necessary.

Final Thoughts

The Gunman Contracts – Stand Alone OpenXR Runtime Error looks worse than it usually is. In most cases, the game isn’t fundamentally broken. It’s simply failing to find the VR runtime it’s expecting.

Start with the boring solutions. Make sure your headset is actually connected, check which OpenXR runtime is active, and make sure SteamVR, Meta Quest Link or Virtual Desktop isn’t fighting another runtime for control. Then move toward API layers and the Windows Registry only when the simpler fixes don’t work.

Personally, I’d avoid jumping straight into a Registry edit just because the error message sounds serious. VR software has enough moving parts already. The cleanest setup is usually the best setup: one active runtime, minimal overlays, a properly connected headset and a consistent launch process.

Once OpenXR is working correctly, Gunman Contracts – Stand Alone can finally do what it was built to do — put you inside a tense, tactical VR firefight instead of making you stare at another Windows error box. And after fighting with VR configuration for half an hour, honestly, getting into the game feels like a contract worth completing.
