Many users encounter problems when trying to use DS4Windows, specifically the error of not being able to open DS4 exclusively. This guide will troubleshoot common causes and offer solutions to get your DualShock 4 controller working flawlessly.
Understanding the "Cannot Open DS4 Exclusively" Error
The "Cannot Open DS4 Exclusively" error in DS4Windows usually indicates a conflict with other programs or drivers attempting to access your DualShock 4 controller simultaneously. This prevents DS4Windows from gaining full control, hindering its functionality. This is a common issue, and thankfully, often fixable.
Common Causes and Solutions
Here are some of the most frequent reasons behind this error and how to resolve them:
1. Conflicting Software:
-
Steam Input: Steam's Big Picture Mode and Steam Input often clash with DS4Windows. Try closing Steam completely before launching DS4Windows. If the problem persists, consider disabling Steam Input for the specific game you're playing.
-
Other Controller Emulators: Avoid running other controller emulators (like x360ce) concurrently with DS4Windows. Only one program should manage your DS4 controller at a time. Close any other controller software before launching DS4Windows.
-
Gaming Software Overlays: Some gaming platforms (like Discord, MSI Afterburner, etc.) have overlay features that might interfere. Try disabling these overlays temporarily to see if it resolves the issue.
2. Driver Conflicts:
-
Outdated or Corrupted Drivers: Outdated or corrupted drivers are a major culprit. Uninstall your current DS4 controller drivers (found in Device Manager under "Human Interface Devices"). Then, restart your computer and allow Windows to automatically reinstall them or install the latest drivers from the PlayStation website (though this often isn't necessary for DS4Windows).
-
Multiple DS4 Drivers: Ensure you don't have multiple drivers installed for your DS4 controller. This is a common oversight leading to conflicts.
3. DS4Windows Installation Issues:
-
Reinstall DS4Windows: Sometimes, a clean reinstall solves the problem. Uninstall DS4Windows completely, delete any remaining files or folders associated with it, and then download and install a fresh copy from the official DS4Windows GitHub repository. Never download from untrusted sources. This is crucial for security and stability.
-
Administrator Privileges: Run DS4Windows with administrator privileges. Right-click the DS4Windows executable and select "Run as administrator." This can grant it the necessary permissions to access the controller exclusively.
4. Hardware Issues (Less Common):
- Faulty USB Port/Cable: Test your controller and cable on different USB ports. A faulty port or cable can cause connectivity issues and conflicts. Try a different USB cable and/or a different port.
Advanced Troubleshooting Steps
If the above steps don't resolve the "Cannot Open DS4 Exclusively" error, try these more advanced steps:
- Check for Windows Updates: Ensure your Windows operating system is up-to-date. Outdated Windows versions can sometimes conflict with device drivers.
- Disable Fast Startup (Windows): Fast Startup in Windows can occasionally interfere. Disabling this feature might resolve the issue (search for "Fast Startup" in the Windows settings).
- System File Checker (SFC): Run a System File Checker scan to identify and repair any corrupted system files (
sfc /scannowin Command Prompt, run as administrator).
By methodically following these troubleshooting steps, you should be able to resolve the "Cannot Open DS4 Exclusively" error and enjoy using your DualShock 4 controller with DS4Windows. Remember to always back up your data before making significant system changes.
