Technic launcher does not load modpacks?

So the following is my problem, I have just installed Technick launcher everything worked out great until I realized then that if I want to play a modpack I can install it but if I press on play yes should the Minecraft window show up but it does not show up it then breaks off immediately and reopens the technick launcher… I have tried everything possible to reinstall from technick launcher to check java by myself have reinstalled java but it just does not work I can garkein modpack open before the modpack can even start mc it lubricates already from someone has a tip for me

Is the modpack possibly very unknown if so it could be the modpack makers change otherwise if I would open the technology launcher with admin right or you know the game in the launcher more RAM
