First off your folder will properly look like this: And when opening the file you see this: Looking at this there is no way to open the Launcher as there are no executable files. To FIX this right-click the Launcher file and go to open with Then you could click Java which will open the file with java and fix the issue. However you would have to do this everytime you wanted to open the launcher. The permanent fix is to click Choose another app, This will open another screen. Now click on java, and at the bottom you will see a box followed by "Always use this app to open .java files". By clicking on the box a tick will appear press Ok. This will open your Launcher in and also correct your launcher and another other .jar files to open in Java. Link to comment Share on other sites More sharing options...
