As another option, some of my plugins have the VST3 version in one of the places music programs tend to look.
For some Kontakt stuff I had to specifically point it to the VST2 version in a different folder.
Luckily for me that folder was clearly labeled .. but the apps didn't find that folder by default; I had to navigate to it.
