Ok sorry to drag this thing out, but I'm no pro with Java. I've recently uninstalled my java versions. Installed Java 7's latest update. I have the Technic Launcher, but it's not letting me update it does the 3 attempts and failed to update thing. I go to click this .jar link OP provided, and I get a JVM error.
Fixed:
After a bit of looking through the computer, and my downloads folder, I did find the .jar's all 11 of the ones I had clicked to download. Chrome was acting as if it was a complete error and not even downloading the file. After I did find the file, I did rename it, put it in the cache folder, and victory was mine. ^.^ Thanks OP
