Thanks,
i thought it would work for any Windows Arm64 Device, but on my Samsung Galaxy Book S it does not work. These arm64-Versions are not listed as installable versions. I made a clean new installation of the Minecraft-launcher and deleted the .minecraft-directory first...
Perhaps adiantek has any clue how to fix it or to run minecraft on this similar Device.
Thanks for your help!
I don't see how it would only work with a Surface Pro X, as you can create custom Minecraft versions on x86/x64 Windows too (or linux or OSX for that matter). I definitely think it should run on your Galaxy Book S, so I have to suspect something must not to setup correctly still.
Just to confirm, you're saving the json file to this location correct?
%appdata%.minecraft\versions\1.17-aarch64\1.17-aarch64.json
For me this ends up being
C:\Users\dom\AppData\Roaming.minecraft\versions\1.17-aarch64\1.17-aarch64.json
I expect your path should be very similar, just with a different username in place of "dom".
Once I put the 1.17-aarch64.json file in that location the next time I opened the launcher I had 1.17-aarch64 listed in the versions drop-down list when creating a new installation.
Also, you could verify the json file did download correctly by opening it in notepad or notepad++ and making sure the contents of the file match what the json file looks like if you view it on github.
adiantek also has a 1.17.1-aarch64.json file on the github page now so personally I'd switch to that just because it's the latest version. And I would name the folder 1.17.1-aarch64 of course.
