stupid me comes again,anyways, i used the -Djava.net.preferIPv4Stack=true on the new jar installer and worked! dunno what made this new file that i installed three times in a row earlier work but it works now, thanks for the help!
im not really familiar with file types but, no, i don't have the jar version of the installer then... i don't know where to download the jar version officially... only the normal ones...
the libraries just won't download is all, i did it all manually since that was the solution that seemed to work for others. i launched the installer normally. i tried the solution from the other thread, where you use the command prompt to fix it, but it still didn't work. all the other solutions i searched for are the same, manually downloading the missing files
So... other threads had solutions that didn't help me, libraries failed to download, so i downloaded each and every one of the scala-lang files, all of them worked except the plugin files... help?
