Old VST 1 FX Plugins not showing on Cubase 12

I have a first-generation version of Waves Diamond Bundle. These are first generation VST plugins. They won’t install into Cubase 12. Does Cubase 12 support first generation VST effects?
If so, how do I make it see the plugins?

No 32 bit plugins work in C12 , the only way is to install 64 bit from V9 upwards
