Extension pack installation failure

[wyzzard47]

I am running VirtualBox version 5.0.4 on a Mac running Yosemite.

VBox is running great, but when I attempted to install the extension pack for version 5.0.4, it failed with the following:

Failed to install the Extension Pack /Users/wyzzard/Desktop/Oracle_VM_VirtualBox_Extension_Pack-5.0.4-102546.vbox-extpack.

Failed to load the main module ('/Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib'): VERR_FILE_NOT_FOUND - dlopen(/Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib, 6): Library not loaded: /Applications/VirtualBox.app/Contents/MacOS/VBoxVMM.dylib

Referenced from: /Applications/VirtualBox.app/Contents/MacOS/ExtensionPacks/Oracle_VM_VirtualBox_Extension_Pack/darwin.amd64/VBoxPuelMain.dylib

Reason: Incompatible library version: VBoxPuelMain.dylib requires version 5.0.4 or later, but VBoxVMM.dylib provides version 5.0.2.

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ExtPackManagerWrap
Interface: IExtPackManager {edba9d10-45d8-b440-1712-46ac0c9bc4c5}


It seems that the incompatible library version issue that I highlighted above is the issue.

Does anyone have any ideas?

Thanks.

It might be a permissions problem. You could repair permissions with Disk Utility and see. I've never had an error installing the extension packs.

Good Suggestion, loukingjr. I tried it, but I still received the same error on installation. I am looking at alternatives. I really want to get a Kali Linux USB stick setup, so I'm going to try it straight from the Kali site and/or from a Windows 8.1 machine.

I'd still like to hear if anyone else has had this issue and, maybe, resolved it.

Thanks.

You may want to take a look at this post. I don't know how it could happen but it looks like it did.
