There are different versions of the launcher available. For most cases, the wrapper should fit your needs.

EXE-wrapper

The Windows executable is compiled from a python script. It checks the system's Java truststore for the DST Root CA X3 certificate. If its available, the system's truststore is used. If the certificate is not found, a local truststore containing only the required certificate is downloaded and the system's truststore is copied into this local truststore.

The script and truststore can be found here.

  • "SKCraftLauncher" in my documents (usually C:\Users\%USERNAME%\Documents\SKCraftLauncher or /home/$USER/.skcraftlauncher)
  • The folder from which the bootstrapper is started, if a file portable.txt is present in the bootstrapper's folder.

JAR-based

Setting up the launcher

When using one of the jar-based launchers, you might need to initially add the certificate to Java's truststore.

Here is how!

Bootstrapper

This is not the launcher itself. Instead it loads the most recent version and starts it. It also automatically updates the launcher.

Minecraft directory:

  • "SKCraftLauncher" in my documents (usually C:\Users\%USERNAME%\Documents\SKCraftLauncher or /home/$USER/.skcraftlauncher)
  • The folder from which the bootstrapper is started, if a file portable.txt is present in the bootstrapper's folder.
