Genymotion is giving me this error after the Windows 10 upgrade:
Unable to load virtual box engine
How to fix this?
After Windows Anniversary update Genymotion stopped working,
It always raised an error dialog saying (not exact but something like this) "Failed to start the virtual machine, Please start Virtual box to see the error details".
I had tried many solutions some of them were saying open Virtual box and make some changes to it, but my issue was Virtual box itself was not starting up explicitly,
I had observed that process starts up and gets killed after few seconds, Then I realized, the problem is actual with a virtual machine.
And when I was looking for it I came across this thread which says there is Bug in the virtual box, just download and install the latest setup file for a Virtual box. Thereafter at least you will be able to start the virtual machine,
After this, if you face some issue you can follow aLoi Ho answer above
