There seems to be many problems with recent releases..

 

Perhaps you got them from a bad source, because they all work fine that we here know of.
What is your OS and what was the release you tried?

 

I actually tried nothing! on sister site - on the newest releases of waves 12 there are comments like: "still missing multiple waves shell files" or "it is still not working" and some long manual that says it works when you make a waves account and download official demos and so on. I was just searching for an easy to install CE

 

You won't be the first person that was at the non-legit copycat site, so I assume nothing.
And it's not because you are new either. Some have been going to the wrong site for years! lol.
If those releases are still up (at the real AZ) then those comments that you chose to fixate on are the minority.
And to be honest, installing Waves was never straight forward.
Anyway, now we've bumped the thread hopefully someone will chime in regards one of the recent releases.
I stayed on older versions.
In answer to your thread title, they all work.
If not, they shouldn't be up.
