Java Problem

The reason why I'm confused is because on a different computer I ran the .jar file and it ran perfectly. The computer only had the regular Java downloaded though...
 
I can only tell you what I know and what I can observe.

The windows %PATH% should contain the directory of the Java JRE & the JDK (if you installed that too).

Recommend you compare the %PATH% of the system that works with that which does not.
