Before moving on the troubleshooting process, make sure you are installing from a local disk (not a USB or an external disk). Moreover, disconnect any game controllers (joysticks, gamepads, steering wheels, etc) from your system as well.
Solution 1: Clean Boot Your System
Applications co-exist in a Windows environment and share system resources. You may encounter the current installation error if any other application is interfering in the operation of VJoy. In this context, clean booting your system (to remove 3rd party interference) may solve the problem.
Solution 2: Restart the Cryptographic Service
Cryptographic service is an essential service for the operation of VJoy. You may encounter the error under discussion if the Cryptographic service is in an error state and is not accessible. In this context, restarting the Cryptographic service may solve the problem.
Solution 3: Revert to the Previous Windows Build
Microsoft has a known history of releasing buggy updates and the issue at hand could be a result of a buggy module in the latest Windows update applied in your computer. In this scenario, reverting to the previous build and then installing the VJoy may solve the problem.
Solution 4: Disable Driver Signature Enforcement
To safeguard its users, Microsoft has made it mandatory for the kernel-mode drivers (VJoy is a kernel-mode driver) to be digitally signed. You may encounter the error under discussion if the VJoy driver is not digitally signed by relavant signatories. In this context, disabling the driver signature enforcement may solve the problem. Warning: Proceed at your own risk as disabling the driver signature enforcement may expose your system to threats or your system may become unstable.
Solution 5: Launch VJoy with Administrator Privileges
Microsoft has enhanced security measures in the latest version of Windows by protecting the essential system files and resources through the implementation of UAC. You may encounter the error under discussion if VJoy does not have the required privileges to access the essential system resources. In this context, launching the VJoy installer with administrative privileges may solve the problem.
Solution 6: Manually Update the VJoy Driver
Your system drivers are updated regularly to cater to new technological developments and patch known bugs. You may encounter the error under discussion if your system drivers especially the VJoy driver is outdated; this causes the system not being able to use it. In this context, updating your system drivers (especially the VJoy driver) may solve the problem.
Solution 7: Reinstall the VJoy Application
You may encounter the error at hand if any of the remnants of the previous installation are causing issues in the new installation. In this context, uninstalling the previous build completely and then reinstalling VJoy may solve the issue.
Solution 8: Reset or Reinstall Windows
If nothing has worked for you so far, then the issue could be the result of a corrupt installation of Windows. In this context, resetting or reinstalling Windows may solve the problem. If nothing has worked for you so far, then try to use another application like Zadig.
