And install NanoFXv2Beta, if you don't already have it.
If I remember correctly, GCv1 has a bug which makes having NanoFXv2 a necessity...
Just remember that you may have to reinstall a couple mods after installing the Foundation and NanoFXv2, GCv1 being one of them. The ships you installed won't need to be reinstalled tho, since they don't use the Foundation/NanoFXv2 scripts like GCv1 (and other scripting mods) do.
