I think some of the most recent updates only install as VST3. At least in my case, these are 9.2 onward and  64-bit only.

Zo, make sure you check the WAVES install directory. You should find all your VSTs in there. I had a similar issue after a full recent update when many of my WAVES plugs were gone from Mixbus which only reads VST and not VST3 ... after finding the right files in the WAVES folder all came back

i cheked on the program 86 folder where it is by default ..and got the waveshell , it's scanning all but few have dissapeared ....form sonar in VST format , thery're here in vst 3

Sometimes Waves Central moves your licences for some reason to the cloud. Once there they will no longer be present on your PC.  Check the cloud licences.  You can easily move any could licences back to your computer.  I had to do this once or twice but it restores things back to normal.
 
My music production computer is offline 99% of the time too so once the licences are back on the computer generally they will stay there.

Licences are all their and good ...nls , ssl E and G , ect are missing ....uninstalling again and re installi,ng i'm tired of Waves ....that's why i didn't updated ...just wanted brauer thing , now i have to handle the same ol meesss , and this on my main desktop , i do'nt even wanna try on my laptop ... :(

Tried it Larry thks i unistalled clean and know how to install , the thing is that the dLL are here but only the vst 3 get registred ...
 
I unistll everything , and then started to install all the newbies one by one , erasing the vst 3 dll to force sonar to use em ...it worked 
 
Then i installed an old version i kept (now i remeber why) waveshell 9.6
 
then some stuff get missing again (F6 and smack attack)
 
we call em tomorow !...

That's what I do Zo, call support. Something doesn't sound right.
