[Technic laucher won't open]

I deleted technic launcher once, because I didnt play it that much. Now I wan't to play it again but technic launcher won't open. I think it won't open because I deleted it wrong. Some files from technic launcher wont get deleted because they say the file don't exist. I tried everything but nothing has worked yet. I hope you guys can help me because I really want to play tekkit again.
