ok

Put it in the Flan folder. If that doesn't work unzip it with winrar or 7zip and put the folder inside into the Flan folder.

how do i install a 7z file?

It would help if you used versions that are compatible with 1.7.10.

AFAIK The only version of his pack that works on 1.7.10 is PG 4.0, 1, 2 and 3 are for older versions and their models haven't been compiled on MC 1.7.10.

I don't think he posted version 4 to Flansmod.com... but you can find it here:

o wait i have it here:

flans 4.9.0 , pokers garage 1.0 2.0 and 3.0 it crashes. should i go to the folder ftblite logs then latest? cuz i never played ftb lite after i posted this.

Right, what version of Flan's mod, what content pack, and can we have the actual crash log?

Again, check the crashlog in your ftb folder.

i opened the console and when i placed it down minecraft closed and said this message in the console.

Check the crashlog and post it here (in a spoiler), can't do anything without it
