Oracle virtual box inaccessible

Question

I am using Oracle Virtual Box version 4.2.16 r86992. Everything was fine until yesterday shutdown. Today, it shows inaccessible and throws this error:

Runtim         


        

Answer 1

On a Windows 7 Host, I found that Daemon Tools service had a hold on the file.

The solution was to uninstall Daemon Tools, but I suspect if you stop the service and remove the file association, you would be sorted.
