This issue was happening for ma also on VirtualBox 4.1.20

What is the type of the partition of C:? NTFS or FAT or anything else? I assume your VirtualBox application installed in 'C:\Program Files\Oracle\VirtualBox'. The extension pack is installed into the 'ExtensionPacks' directory within the applications directory. Does that directory have any special permissions or is it located on an external drive or something like that?

[mkucharski]

Drive has one NTFS partition. I didn't change destination path during installation and VirtualBox is installed under:

c:\Program Files\Oracle\VirtualBox\

I had other issues with VB after upgrade to 4.1.22, so I've decided to uninstall everything, remove extensions by hand (no uninstall option, from VB installer?) from above location and install 4.1.22 again.

All works now, however I didn't install extensions again, as I don't need them anymore.

Closing as duplicate as there are other reports. Actually it looks like the directory where the extension pack was stored is not writable by the Administrator.

Exactly the same issue for me today. I have first upgraded my Oracle VM BOX to 4.1.22.r80657 on my W7 Pro 32 bits. I am logged as a user with admin rights. Then once installed and when I started it, I had the message about the possible upgrade of the extension pack. I asked to get it and I had the same errors. After multiple tries, I have stopped Oracle VM Box. I have found the folders "C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack" "C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack - Uninst" (or something like this). I have renamed the second one and retried the update. This time it worked. Then I have deleted the old folder.

There is obviously a flaw in the installer. If the uninst folder exist, it should delete it. I suspect that after the upload it tries rename the main folder to uninst, does its install then if everything is fine delete the uninst folder. If the install fails, uninst become what is was as this is the solution to rollback to a good state. With uninst present before the upgrade and not deleted, everything fails.
