VBox notified me my extensions were out of date and I successfully downloaded the r20 version. It started trying to apply the update and failed with:

Failed to install the Extension Pack C:/Documents and Settings/xxxx/.VirtualBox/Oracle_VM_VirtualBox_Extension_Pack-4.1.20.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}

Any thoughts?

Thanks,

Morepork.

I have the same problem with the same outcome but a slightly different error code. Is there a way round this problem?

Failed to install the Extension Pack C:/Users/Peter/AppData/Local/Temp/Oracle_VM_VirtualBox_Extension_Pack-4.1.20.vbox-extpack.

Same here, never had this problem with old versions. I am trying to update from 4.1.20 to 4.1.22.

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

As indicated by the error message, it failed to rename the existing folder.

An empty folder by the same name, with _-uninst added, already exist in the C:\Program Files\Oracle\VirtualBox\ExtensionPacks directory.

Just delete the empty Oracle_VM_VirtualBox_Extension_Pack-_-uninst directory and 4.1.20 will uninstall, allowing 4.1.22 to install.

Me too got the same problem, Any advice from VBox team ?
