Hia,
Which version of Waves Complete should I download for a stable experiance on Windows 11?

I've been using v9.6 2016.05.18 on Windows 10 and It's been fine.

Cheers

 

That is version is quite dated since the current rev's are now up to v14.xxx. That said, considering that the core of waves plugins hasn't changed much in the interim from v9.x to 14.x you can probably use that v9 one successfully in win11 as well. There's a few of the "newer" what I call sucker plugs that require connecting to waves servers in order to use them. Since I do not allow production machines to have an internet connection those sucker plugs are simply moot. However if you're running the main core of the Complete line up I don't see why the latest version shouldn't run well on win11. As always with scene releases, active internet connections, A/V, autonomous OS update services, etc, can be problematic for any OS platform. Just fyi...
