virtualbox.org

This is a fully reproduce-able Critical Error window
"Failed to create the VirtualBox COM Object"
The application will now terminate
Calee RC somethingsomething...

HOW to Do IT:

I did a compact operation as root.
it somehow locked up folder so VirtualBox could not open from the normal user the following folder and the error ensued.

Just deleting the locked up folder cleared the mess. -----------

Additional "Critical Error" detail:

Callee RC: RPC_S_SERVER_UNAVAILABLE (0x800706BA)

VirtualBox Version: 1.6.2
Host Platform: WinXP Professional Version 2002 Service Pack 2

Solution:

Start the "DCOM Server Process Launcher" service.
Note: VirtualBox must be installed as admin.

ADMINISTRATOR: This thread really needs to be moved to the Linux Hosts forum, except for asifhv's post.

I had the same error when trying to start VBox, and I found that I had a locked folder in the /tmp folder too.

Folder location:
/tmp/.vbox-[user]-ipc (where [user] is your VBox user name)

Deleted it using: (again, where [user] is your VBox user name)

Worked again...Yea! Thanks mcpatnaik!!
