sorry for saying it so late
if i click download it will download
but how do I open the studio, I tried to open it.
and click the bad folder. and i used the code with
cd <i have written the place of the follder> java -jar launcher.jar
in cmd
Now you unzip the folder, place the folder somewhere on your PC and double click launch.bat or launcher.jar (whichever works). You need Java 8+ to be installed on your PC for BBS to work.
