Install Tekkit on original minecraft

[Yap7]

Hi, the technic launcher don't perfectly work with me, so I want to install Tekkit on the original Minecraft, so I'll can launch the game directly with Minecraft.

How can I do that? I understand nothing about installing, so I need to be guided step by step, it's useless to just send me a link, I need to have clear explications.

Tekkit is server mod, not a client mod, and in order to use it, you must also use Technic launcher.

Sorry, it looks like you need to ask about resolving your Technic Launcher issues as I don't think Tekkit is your solution.

Ok, I see, thanks.

I don't think my problem with the launcher can be resolved, it's happen when I try to capture a video, the game is closed instantly when I try to launch the reccording.

You can use the original launcher but it the interests of stopping piracy. I won't say how to.
