Ok, so if you have the same installer, that's weird... What you see in the about dialog is the Corona for C4D plugin version, whereas the VFB is a part of the Corona Core, so it shows the Corona Core version. You probably have different Corona_Release.dll than your friend. What I'd suggest would be uninstalling Corona, erasing the plugins/corona directory from the C4D folder and installing again. I guess the installer isn't able to update the core .dlls.
If you want to help us debug this issue, try to find out, whether the Corona_Release.dll and CoronaLib_Release.dll files that you have in the plugins/corona folder are the same ones that are bundled within the installer (you can find out by just extracting the contents of the installer somewhere).
