What is the cause of the “supR3HardenedWinReSpawn” error in VirtualBox?

One of the most common reasons for this behavior is a missing driver (VBoxDrv.inf). It is possible that due to authorization issues, the installation of this important driver was not completed during the initial installation. In this case, the problem can be solved by manually installing the VBoxDrv.inf file.

Another possible cause of this error is an anomaly in the registry pointing to the wrong driver directory. If this scenario applies, you can quickly fix the problem by performing a registry check and correcting the ImagePath line if the directory is incorrect.

One of the most common causes of the VirtualBox “Error in supR3HardenedWinReSpawn” error is a missing driver (VBoxDRV.inf). It is possible that the main VirtualBox application is installed without this important driver due to an access rights issue.
