I looked around and saw that all the threads that were asking for help were for people developing a program using the java language, so I'm not sure I'm in the right section. But anyways, when I try to open a .jar file it says a default program is not chosen. When I go java>jre7>bin>javaw it sets it as the default program to launch it. But when attempting to launch the file, it just lanches the java update thingy. (Do you want the following program to make changes to your computer? File name: Java SE Runtime Environment 7 Update 6) I've been having this problem for a while now. I tried re-installing java, using jarfix, etc. but couldn't find the solution.
