You have to run the whole .jar file you download, not anything inside it. Some uncompressors *cough* winrar *cough* tend to think that jar files are regular compressed files and they show you the stuff inside it because they associate the jar extension with themselves instead of Java.

I should make an exe version since this seems a common issue
