I used Virtual Box, then decided to delete it. I put it in the bin, but then i decided i might need it later, so i pulled the application out and put it on my desktop. Since then I can't remove the application. When I try to do so i get the following error: "The operation can’t be completed because “VirtualBox” needs to be downloaded." .
So i downloaded it, tried the uninstallation tool that the Virtual Box provides, but that didn't help either. Any suggestions?
