I also can’t change the installation path, the installer won’t let me do it
What location are you downloading the launcher from?
via the beam mp website
Did you unpack the .exe from the .zip before running it?
yes, I did that but still can’t select the download directory
Download Launcher v2.0.82 from GitHub and place it where you want BeamMP and cached mods to be installed
