Welcome to the Cryptomator community :slightly_smiling_face:

Cryptomator requires a certain Windows feature to run, which was introduced with Windows 1803 (or better, build 17134): UNIX sockets.

If this feature is deactivated on your Windows system, you cannot use Cryptomator.

Currently running Windows 10 22H2 Build 19045.3086 and the “Windows Subsystem for Linux” feature is also enabled.

I’m not exactly sure how to enable/disable the feature @infeo mentioned, but I’m pretty sure enabling/disabling windows subsystem for linux is irrelevant to the specific library/feature that is required for Cryptomator to run on Windows.

I have never enabled windows subsystem for linux and Cryptmator works fine. I have also never disabled other default features. You may need to investigate other non-standard features/settings you have made to your windows setup.

I also don’t know how to enable (let alone disable) that feature. It might not even be listed in the “Windows feature” list. My only suggestion would be the reset-everything-tool: Reinstall Windows.

Following @infeo 's link regarding UNIX sockets, it seems this may be an issue with AF_UNIX service:

http://revertservice.com/10/afunix/

However, I’ve been unsuccessful in my attempts to repair/reinstall the afunix service in Windows. May just have to reset-everything barring any other useful tips on this matter.
