I can't open jar files
Hello.
I'm a Minecraft fanatic and I've been trying to install mods for like forever, but I get stuck when I try to open the .jar files of the mods.
I get this message:
The Java JAR file "<file-name>" could not be launched.
Check the Console for possible error messages.
I can't open any other .jar file on my computer either, which is really annoying. I've checked a lot of other discussions on this forum that ask the same question but none of the answers or suggestions help/work. Is there any way I can fix my computer/jar files so that I can run the files to install them into my game?
Mac OSX 10.8.3
No idea what Java version it is because I can't find Java for some reason. I'm pretty sure I have Java though
