Need help with Virtual Box error message

Asked By 0 points N/A Posted on -

I have installed VirtualBox a while ago and It was working perfectly but recently I was trying to launch VirtualBox but an error message appeared instead, the message was:

Failed to create the VirtualBox COM object. The application will now terminate. Callee RC: 0x80040154


Failed to create the VirtualBox COM object.
The application will now terminate.
Callee RC: 0x80040154

I have tried to reinstall VirtualBox version, upgrade the actual version and even get another version but the same problem occurred. I would really appreciate if you help me on this and thank you.

To solve this problem you must have an Uninstaller software because windows Uninstaller only uninstall some of the programs but not all of its root program. First you have to download an Uninstaller software such as Revo Uninstaller. Install the software and then uninstall the virtual machine and then scan all the related files for this program and delete all the files. Now install your virtual machine whatever version you have it will work correctly. The main problem you were having some corrupt file in older setting. And when you uninstall them virtual machine that files remain still there.

Hello Caram1,

Although you did not mention what your host operating system is, your screenshot suggests that you are running Fedora as your host operating system. 

"Failed to create the VirtualBox COM object." means that somewhere there is a file that is interfering with the startup of VirtualBox.

I Googled for "Callee RC: 0x80040154" and the solution is to remove some VirtualBox temporary files. To delete those temporary file types this within a terminal window:

sudo rm -rf /tmp/.vbox*

Another solution is to restart the guest operating system (the OS clears the temp folder during restart so it's the same thing as the first solution).
