If you are moving an older version of Waves (Version 9.2) to a new computer, simply copying the .vst3 file usually will work.
The 92 in 92x64 is shorthand for the shell version – here, version 9.2 or 9.92. Older shells might show 9.7x64 , 10.0x64 , etc.
Waves plugins rely on a centralized licensing engine installed in your Program Files. If you copy just the Waveshell file without installing the Waves Central application and the license files, the shell will open, but no plugins will appear inside it. You must install the software using the official Waves Central installer for Version 9.2.
