VirtualBox won't open. Here's what the error says:
Failed to create the VirtualBoxClient COM object.
The application will now terminate.Callee RC: REGDB_E_CLASSNOTREG (0x80040154)
Screenshot:
It all started when I tried to install "Xamarin Android Player" and it installed a separate version of VirtualBox (I was originally on version 5.0.12, it tried installing version 5.0.4), so I tried opening it and it failed. I tried opening VirtualBox and I got that error, and it kept giving me that error through every version I installed (2.2 to 5.0.15) and I'm completely stumped.
My specs:
What can I do?
You will have to uninstall that Xamarin player AND Virtualbox completely.
Then remove all traces of both that may have been left behind (Revo Uninstaller is a good tool for that).
If you have a system-restore point dating from before you attempted to install Xamarin it may be less hassle to go back to that.
Reboot and then FIRST install Xamarin, then VirtualBox.
Oldest version FIRST.
It is possible that that combination doesn't work either. If that is the case you will have to again completely uninstall both and then decide which one you really need and only install that.
Please note: Because you have been trying multiple versions of VirtualBox without cleanly uninstalling any of them it is possible your Windows installation is already damaged to the point it is no longer possible to get back into a clean state. If that is the case you hopefully have a restore point dating from before the time problems started. If not a re-install will be needed...
I actually fixed it... all i had to do was delete the ".virtualbox" folder in "C:/Users/"User"/.Virtualbox:(replace "User with your account's name"
thanks for the help guys. I really appreciate you guys giving me advice.
I havve solved the error:

G to your USER folder ie Document&settings or Your Username folder
You will see the .virtualbox
folder
Click on that folder and remove the virtualbox.xml
file and the virtualbox.xml-prev
file
Again run vbox
, it will automatically create the above file and it will run perfectly.
