Reinstalling Extension pack failed

[riker1]

Hi
Try to install Extension pack
Message says it is installed, and will try to reinstall:

File is available of course:

Any ideas?

thanks

(Strange wise is VBOX not recognizing that extension pack is installed already)?

Error message while reinstalling

Which version of VirtualBox do you have installed? To me it seems that you have VirtualBox 4.3.x installed and try install the Extension Pack 5.0.14 which would not work.
