Plugins no showing up in Cubase

I just recently downloaded a few new effects plugins.

most of them are showing up in cubase but a few are not. Specifically the SSL LMC-1 compressor, Blockfish, Floorfish, and Spitfish, and the Ambience reverb.

I’m pretty sure the VST files are in the correct folder (they are in the same folder as all my other plugins which are working fine)

I don’t know what to do to make them work…

64 or 32-bit host?
What folder did you put them in?

SSL LMC-1 compressor, Blockfish, Floorfish, and Spitfish, and the Ambience reverb.

If you’re on OSX…specifically 10.7 or 10.8, that’s it for these plugins. They are PPC and won’t run whatsoever because Apple removed the “Rosetta” PPC bridge from the OS. You’d need to operate Cubase 7 (or earlier) in 10.6.8 in order for these to run.
Regarding the Fish Fillets package: The developer has stated that he never intends to update these, as he now works fulltime as a programmer for U-He.

If you’re on a PC, they may run in 32bit mode. Dunno.

I was sorry to see Blockfish go when I pushed into 10.8. It had a nice “spit” attack, reminiscent of the slow attack mode of an SSL E or G series console.
