Arturia analog lab in Cubase 2.1


I’m using a very old version of Cubase (but works fine!)
I have Analog lab installed, but cannot open it as a VSTi.
In the plugins list it appears at the bottom, but whilst the other have a tick at the far right side, this doesn’t have a tick. If I manully tick it, it doesn’t seem to help. It seems that Cubase finds it, but doesn’t launch it.
Does anyone know any solution for this?
Many thanks
