Failed to create the VirtualBox COM object.

After upgrading VirtualBox it comes up with the error below. At first I figured it was a corrupt installation of the product (VirtualBox v4.2.0), I uninstalled, restarted, reinstalled - same deal. I have also downloaded an older version (v4.1.18), uninstalled, restarted, reinstalled and am getting the same error.

I've found a few issues online similar, but nothing that looks like it can help me with this. I'm using the product with ShadowProtect in a backup / disaster recovery environment, so it's pretty essential I get this up and running as soon as possible in case of failure.

Operating System: Windows 2008 R2 SP1
VirtualBox Version: 4.1.18
Disk space: 112/147GB (C) + 44.6/931GB (E)

Any help at all to push me towards the right way to get around this would be great.

Thanks,

I have a little update, I uninstalled all of the related applications - VirtualBox, ShadowProtect, ImageManager, deleted all of the related left over files manually, restarted, then reinstalled VirtualBox and then I got a different error! (as below)

Anyway, I ended up deleting the .VirtualBox folder (why didn't I think of this before?) which had an OLD VirtualMachine in it that was no longer used / files were missing, once I did this, the application came good.

I'm guessing since the upgrade of the software, it was attempting to search for the old VirtualMachine content and couldn't find it and bam!

I hope this helps someone in the future with similar issues.
