I have installed VirtualBox 4.0.2 on a Compaq Presario Windows Vista host that was the current GNU version when installed.
I have a Linux Mint 10 guest with 4.0.2 PEUL Guest Additions installed.
When I tried to install the extension pack version 4.0.2 I ran into a problem the agreement buttons on the license are grayed out making it impossible to install the package. Also, install Extension Pack is not listed under Devices in VirtualBox.
I had the same result with VirtualBox 4.0 and reinstalled VirtualBox and the guest several times
I have not tried version 4.04 yet. Can anyone help?
