"Many companies buy new licenses then install old, sometimes unsupported, versions of PxPlus."
So if I order new keys for an old ProvideX ver5 user, and they will continue to use that older code, I should use the Activation Key not the PxPlus Key?
Also, for that user running old ProvideX v5 code, should I order Base or Pro? Would Pro work on that old user? Or is Base and Pro the same code wise?
