Why won DrJava start on Windows?
If you get an error message from Windows when running DrJava (before the DrJava splash screen appears), you probably either do not have Java installed or it is not configured correctly. First, ensure that you have installed the Java Software Developer Kit (SDK) and not just the Java Runtime Environment (JRE). If you still cannot run DrJava, try downloading the “Jar File” rather than the “Windows App” from the DrJava home page and double clicking on it. If Windows asks you which program to use to open the file, select “javaw.exe” (which should be located in “C:\Program Files\Java\j2re…\bin\javaw.exe” or a similar folder).
