VirtualBox upgrade error

I've decide to update my old version of VirtualBox on Windows 7. The installation of the software went fine but when I tried to update the  Extension Pack I run into this issue:
Failed to install the Extension Pack C:/Users/rado4752/.VirtualBox/Oracle_VM_VirtualBox_Extension_Pack-4.2.10.vbox-extpack.

The installer failed with exit code 1: VBoxExtPackHelperApp.exe: error: Failed to rename the extension pack directory: VERR_ALREADY_EXISTS


Result Code: E_FAIL (0x80004005)
Component: ExtPackManager
Interface: IExtPackManager {3295e6ce-b051-47b2-9514-2c588bfe7554}

As the error suggest this is most likely a file system security issue. As I don't have full Admin right on this host the solution for me was to clean and uninstall the old Extension Pack before trying to install the new one again (more info about it can be found here:
c:\Program Files\Oracle\VirtualBox>vboxmanage extpack cleanup
Successfully performed extension pack cleanup

# try to install the Extension Pack again
