Having trouble starting Tekkit

[Azraels_Raven]

So i tried to load up Tekkit yesterday after a friend invited me to a server he was running. I selected Tekkit and hit play. The files loaded for about five or six minutes then the launcher disappeared then popped up again as if nothing had happened. I tried re-installing technic pack, i tried uninstalling my virus protection and i allowed technic pack to work with my firewall and it's still not working can anyone help me please?

Those few minutes were likely spent downloading the modpack. If the game then closes immediately after launching, this may be another case of wrong Java version. Java 7 is still recommended to run Tekkit (currently update 67), and there is a known issue that will prevent the game from starting on Java 8 (update 20 and newer).

 

If that's not it, please take the issue to the tracker, and try to gather >crash logs.
