Can't run JAR file
<p>I have a finished program that I created a JAR executable from (I created this in eclipse), and I need to download this executable onto computers different from the one that I wrote the program on. </p>

<p>However, I am getting the problem that when I try and download the executable onto the computers, I get the window that pops up that says that "Windows can't open this file" and it then gives me a list of programs that I can open the file with, none of which I can use. I do not need to do this on the computer on which I wrote the program. When I double-click the executable on that computer, the program starts without any trouble. </p>
