VirtualBox : Update Extension Pack failed, 0x80004005, VERR_ALREADY_EXIST

 

Failed to install the Extension Pack ~~/Oracle_VM_VirtualBox_Extension_Pack-4.1.10.vbox-extpack.

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

rcExit=1.

Result Code:
E_FAIL (0x80004005)

Component:
ExtPackManager

Interface:
IExtPackManager {3295e6ce-b051-47b2-9514-2c588bfe7554}

 

 

The work around was to delete the folder:

~~\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack-_-uninst

After that all went well, uninstall and install the new extension pack of latest version.
