For anyone who is interested, I like the mod KS Hairdos - HDT SMP (Physics), which requires HDT-SMP(Skinned Mesh Physics) which probably will never be updated for the GOG version.
Use instead this mod: FSMP - Faster HDT-SMP. Here is the link to the GOG version of this mod

I have only tested it on the KS Hair physics as I do not use any other jiggle mods

I can confirm that this works, thanks. Physics is very important in Skyrim for... physics-y things.

Virustotal flags this (1/90 but still) as infected

The same can be said for the file uploaded to Nexus in January 2022 (2/55 ... trojan/bitminer) - you can click the green checkmark to see the virustotal report:

Unsigned files will almost always be flagged: if there is no valid digital signature, it's not possible to know which company modified it, so it is possible that the file may be malicious - but it doesn't mean it is.
Most tools don't actually check what's inside the file itself.


TL;DR: most likely a false positive.

Thanks for link. now my hair works and game does not crash while choosing hair style

Can this serve as a replacement for other physics mods? Actually, I seem to be unable to get the physics version templates to show up in bodyslide at all.

I would think that, yes, it would be a complete substitute for HDT-SMP. But you should first check your CBBE setup. I use MO2 and on my GOG Skyrim install, I can see the CBBE physics templates. If you find that you need to use XPMSSE, you will need to find a way to make FNIS work with the GOG version. I haven't been able to find a method on the internet, but Nemesis will work as a substitute for FNIS (in most cases). Which mod manager do you use?

2.4.4 is the current version, but you need the GOG and EPIC support update file.
A different version of game_skyrimse.dll to overwrite the one in your MO2 plugin's folder.
