Win7: Update Extension Pack 4.0.6 -> 4.1.0 failed, 0x80004005, VERR_ALREADY_EXIST -> fixed as of 27 may 2014 in 4.3.x and later releases

[Marek]

Hello,

I´ve got the following error after updating from VirtualBox 4.0.10 to 4.1.0:

If I try to update the Extension pack to current version 4.1.0 the update starts, but then it fails with the following error:

"Failed to install the Extension Pack" The installer failed with exit code 1: VBoxExtPackHelperApp.exe: error: Failed to rename the extension pack directory: VERR_ALREADY_EXIST

rcExit=1

Details

Result Code: E_FAIL (0x80004005)

Component: ExtPackManager

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

See attached screenshots (s1, s2).

• VirtualBox was started as Administrator

The old Extension pack can also not be uninstalled; while i tried to remove it a similar error occures (see screenshot s3)

Further informations about used versions:

Host: Windows 7 Professional 32bit SP1

Previous Version:

VirtualBox-4.0.10-72479-Win.exe

+ Extension Pack 4.0.6 (because it was not updated before)

Info:

After renaming the folder

C:\Program Files\Oracle\VirtualBox\ExtensionPacks to \ExtensionPacks.sik

and restarting the application the list of installed extension packs was empty.

Now i could install the extension pack for version 4.1.0 correctly :-)

workaround works!!! even for 64 bits versions :)

I've encountered that same error VERR_ALREADY_EXISTS when try to uninstall extension pack of version 4.0.1 while Virtual Box version is 4.1.8
The work around was to delete the folder:

C:\Program Files\Oracle\VirtualBox\ExtensionPacks\Oracle_VM_VirtualBox_Extension_Pack-_-uninst

After that all went well, uninstall and install the new extension pack of version 4.1.8.

Host OS: Windows 7 32 bit.

Great finding. Though I still don't know why the old _-uninst directory isn't correctly deleted. This works here, I've tried to reproduce this on a Windows 7 host.

See my comments in https://www.virtualbox.org/ticket/10906#comment:6

You may have an "Oracle_VM_VirtualBox_Extension_Pack - uninst" directory present in which case the installer cannot rename the existing "Oracle_VM_VirtualBox_Extension_Pack" to it. Delete/rename the uninst folder and retry. Have admin in rights to do it.

The installer should take care of this.

Still not fixed. VirtualBox 4.3.0, Win64.

Not sure why this happens yet, but we've come up with a workaround that we hope will help. Will show up in the next 4.3 and 4.2 bugfix releases.
