Gnutella Lite is written in Java, which is not a native programming language for Windows. For this reason it must run in a Runtime Environment (distributed by the creators of Java, Sun Microsystems). The JRE is distributed with Gnutella Lite, and alternately the download is available free from our download page. It's rather large, but necessary to run Gnutella Lite. Version 1.3.1 is the default version of the JRE, and is the smallest download (5MB)- it is recommended. Version 1.4 is a newer version, and adds some functionality and speed to Gnutella Lite, but has not been tested as thoroughly- also it is a larger download (9MB).
Java programs like Gnutella Lite generally take longer to load user interfaces than applications programmed in native Windows code. Once Gnutella Lite loads up it will function and perform as well or better than other non-Java programs, however. Make sure you are connected to the Internet before attempting to run Gnutella Lite.
