Virtual box critical Error

I wonder what cause this error, I just run VirtualBox after installation, I tried re-installing, repairing, upgrading version, downgrading version. But this error keeps coming up.

  • This error will also occurs if the Windows Environment Variable VBOX_USER_HOME is improperly set. – user496886 Sep 13 '15 at 16:35
  • In my case I needed to open Virtual Box as an administrator. Right-click on the shortcut to open it, select "Run as administrator". – James T Snell Mar 16 '16 at 18:10

According to this article, this can be fixed like so:

  1. Open a standard command line ( Run > cmd )
  2. Run: cd C:\Program Files\Oracle\VirtualBox
  3. Run: VBoxSVC /ReRegServer
  4. Run: regsvr32 VBoxC.dll

Make sure to run the Command Prompt as an Administrator.

But I find it confusing that this happens directly after installation. You may want to report this issue on the VirtualBox Bugtracker.

  • Thank you for your help, but I can't do step 3, and when i do step 4 it give me the following message "The module "VBoxC.dll" was loaded but the call to DllRegisterServer failed with error code 0x80070005" . And i don't know why but i can't access www.virtualbox.org any page from this domain. – Thu Yein Tun Jul 28 '12 at 10:25
  • @TitanZack: Why can't you do step 3? – Der Hochstapler Jul 28 '12 at 12:40
  • I can't do that because cmd says VBoxSVC is not recognized as a command. By the way do you have any idea why i can't access www.virtualbox.org and any of it's subdomain? – Thu Yein Tun Jul 28 '12 at 14:32
  • @TitanZack: Try VBoxSVC.exe. No idea about the connection problem. Site works fine here. – Der Hochstapler Jul 28 '12 at 14:52
  • I don't have that file. – Thu Yein Tun Jul 29 '12 at 14:38

I have the same problem after de+reinstall VirtualBox.

Good hint, Oliver Salzburg! It didn't work for me under Win10, but brought me closer to the solution:

  • Open start menu, right click on the VirtualBox link
  • click on 'open file path' - explorer opens
  • Right click on VirtualBox link, then 'settings'
  • under 'compatibility' click 'settings for all users' button
  • check 'execute program as administrator'
  • ok-click all windows

'Strings' may vary due to translation.

Surprisingly (for me), 'execute program as administrator' even makes a difference when using an admin account. This is also important for Oliver's solution (as I learned today after >15 years Windows experience.

This error occurred with my win 7 64 bit too.

I came to a conclusion that this problem occurred due to installation of youwave for android on my pc.

They both have some conflicts so only any one can be installed at a time.
