CKAN VS Launcher

Try downloading from ckan. I had the same error when downoaded this mod from spacedock. I deleted it, then got it from ckan, and it worked perfectly for me.

Download CKAN here: https://github.com/KSP-CKAN/CKAN/releases

i cant find the download button. after i open this link : https://github.com/KSP-CKAN/CKAN/releases/latest i dont know where to look.

CKAN is what most people use, and it works on Linux (it's basically a package manager). How you install it depends on the distro, but it's all in the link.

You'd need to install with CKAN (Sooooo good!)

CKAN: https://github.com/KSP-CKAN/CKAN/releases

If these are the first you want to install, go to your Epic library and check the 3 dots, you should see where your game is installed, then give this information to CKAN.

Here is a link to Modloader for MCb173. It needs adding directly into the minecraft.jar file, however if you use a launcher like MultiMC, which you can find here: https://multimc.org/ then there is an option to 'add to minecraft jar file' which does the same thing.

I used to have this issue lots, and it was due to my internet being too restrictive. The Minecraft Launcher was refusing to open, and I fixed it by messing with the restrictions until it worked. Hopefully this helps :) if all else fails of course, try just reinstalling it! I’m sure that all your config files don’t get affected by reinstalling it, but just in case make a backup. And if all ELSE ELSE fails, you could switch to a completely different launcher, like MultiMC! Good luck!

If you are willing to try out the launcher - MultiMC which you can find here (there is a Mac option available) : https://multimc.org/ then I have put together an MCb173 pack that has been made for MultiMC. You just use the 'import from zip' option.

Download MultiMC from their official site https://multimc.org/

Others than that, if you insist, you can take a look at the launcher which u/reginakinhi provided or find others on the internet (GitHub for example). Since PrismLauncher is written in C++, and if you are not familiar with it, you should see other launcher as well. Or else https://github.com/MultiMC/Launcher is an alternate.

The best way to experience beta 173 is to play beta 173, and perhaps add some mods to it a little later. One of the better launchers to use for old versions and for playing modded is to use the MultiMC launcher which you can find here: https://multimc.org/

This will only assist if you are using MultiMC as your Minecraft launcher as it is a MultiMC instance which you can use the 'import from zip' option. MultiMC can be found here: https://multimc.org/ It includes IC2 1337 with several add-on mods which have also been back-ported to work with it, such as the Thermometer, Advanced machines, etc. You can disable the add-ons you do not wish included. There is also buildcraft and redpower added as well.
