[FIX] vJoy Failed to Install

You may fail to install VJoy mainly due to incorrect driver signature enforcement. Moreover, the corrupt installations of Windows or VJoy may also cause the error under discussion. Some users faced the issue while updating the application as well. The issue is reported to occur on nearly all versions of Windows, starting from Windows XP.

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 3^rd party interference) may solve the problem.

1. Clean boot your system.
2. Then try to install the VJoy to check if the installation issue is resolved.
3. If not, then restart your system.
4. Upon restart, again try to install the VJoy but without all the companion applications and check if the VJoy is clear of the error.

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.

1. Right-click on the Windows button and in the resulting menu, click on the Task Manager.

   

2. Now navigate to the Services tab and find the CryptSvc.

   

3. Then right-click on the CryptSvc and in the context menu, click on Restart.
4. Now try to install the application to check if the installation issue is resolved.

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.

1. Press the Windows key and type Settings. Then in the list of search results, click on Settings.

   

2. Now, click on Update and Security and then click on View Update History.

   

3. Then click on Uninstall Updates.

   

4. Now select the problematic update and then click on Uninstall.

   

5. Now wait for the completion of the uninstallation of the update and then restart your system.
6. Upon restart, check if you can install VJoy successfully.

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.

1. Type Settings in the Windows Search bar and then in the list of results, open Settings.
2. Now click on Update & Security and then, in the left pane of the window, click on Recovery.

   

3. Then click on Restart Now.
4. Upon restart, click on Troubleshoot.

   

5. Then click on Advanced Options.

   

6. Now click on Startup Settings and then click on the Restart button.

   

7. Then Disable Driver Signature Enforcement by pressing the corresponding key and restart your system.

   

8. Upon restart, check if you can install VJoy.
9. If not, disable the secure boot and then try to install the VJoy to check if it is clear of the error. You may have to disable driver signature enforcement whenever you want to use VJoy.

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.

1. Disconnect any VJoy related hardware from your system. Moreover, make sure no VJoy related process is running in the Task Manager.
2. Now try to install the VJoy. If it fails, download the zip file from the VJoy site.
3. Then unzip the archive and copy its contents to the installation directory of the VJoy. Usually, it is:

   C:\Program Files\vJoy

4. Then right-click on the vJoyInstall.exe file and then click on Run as Administrator to check if the installation issue is resolved.
