Please if anyone can point me in the direction of a step by step fix

Check that your extension Pack version matches your Virtualbox version.

I have reinstalled 3 different versions of VB
version 6.1_6.1.12
version 6.1_6.1.16
version 6.1_6.1.18 and an extension pack but the error still persists

Version 6.1.12 r139181 (Qt5.12.8) is installed


6.1.12r139181 extension pack is installed

RTR3InitEx failed with rc=-1912 (rc=-1912)

The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing

'/sbin/vboxconfig'

may correct this. Make sure that you are not mixing builds of VirtualBox from different sources.

where: supR3HardenedMainInitRuntime what: 4 VERR_VM_DRIVER_VERSION_MISMATCH (-1912) - The installed support driver doesn't match the version of the user.

Also check that the Linux kernel headers are installed. https://www.virtualbox.org/manual/ch02. ... nux-prereq
