Should Avisynth work on Windows Server 2022?
After installation, it doesn't see the plugins ("unknown function ffms2", etc.), even though the plugins are in the correct plugin64 and plugins64+ directories.
Could some non-functioning plugin be causing this message? (Poor Windows Server, it doesn't even play H264).

It works like a charm over here on Windows Server 2022 Standard x64.
The most likely reason is that you're missing the Microsoft C++ Redistributable, which is one of the very first things I install whenever I deploy a new machine.
You can use the AIO repack as long as you trust ricktendo and abbodi from the MSFN community (or you can go through the tedious task of downloading and installing each and every version manually).

You can also use Dependency Walker to drag and drop a dll or an exe to it and see if you're missing any functions and/or dependencies.

In general, Avisynth works from Windows Server 2003 all the way up to Windows Server 2025. :)
(Windows 2000 Server support was dropped after Avisynth 2.6.1 in 2016, so basically when we moved from the classic Avisynth with 16bit stacked and interleaved to the new Avisynth+ with planar high bit depth up to 32bit float).
