Great, I didn't expect to get stuck so early on. I installed Virtualbox with no problems and tried to install the extension. However, this gave me the following error messages:
The extension pack is already installed with the same version. Would you like to reinstall it?
Chosing YES as I've certainly not installed it before gives me: Failed to install Extension Pack
VBoxExtPackRegister returned VERR_VERSION_MISMATCH, pReg=0000000000000000 ErrInfo='VirtualBox version mismatch - expected 5.0 got 5.1'.
How do I check what is installed and how to fix this, if necessary at all? I downloaded both Oracle VM and the extension pack a couple of days ago together.
edit: looking into the Preferences of VB I see that the extension pack 5.026r is installed, which seems to be the one I downloaded, and which just refused to get installed.
