Technic Launcher not opening?

[Sinjection]

Installed Technic yesterday, and it worked fine with the Technic modpack while on a friend's server. Come today, I can't even open the launcher. By which I mean if I click on the icon on the desktop, a loading icon for the cursor appears for a fraction of a second and then disappears. The same will happen if I attempt to open via Command Prompt. The only thing I've done so far is install a 64-bit version of Java. However, I've found I can't open any of the Java apps that came when I installed the 64-bit version. Anyone have any suggestions?

Open command prompt and type "java -version" if it says its not recognized than you should uninstall/reinstall java and make sure its in your system path variables. If it displays something like "Java(TM) SE Runtime Environment (build 1.8.0_60-b27)" then I would make sure you have a 64-bit system and if you don't uninstall the 64-bit java and grab a 32-bit.
