"Error in opening zip file"

[Asticol]

Hello,

This is the third time making a modpack (the other two have failed rather miserably) and I have never encountered this issue before. I was wondering how I would fix this.

I've done a lengthy google search, tried multiple solutions which have not worked well. I would appreciate any help I could get. I am aware that, once the issue is fixed, there may be some conflicting ID's too, which I would also need help with.

Here's the modpack URL: http://www.technicpack.net/modpack/butter-loving-fun-pack.854589

Many thanks,

- John

Where did you get all these mods from? A few mods I see under the "mods" folder aren't normally in a .zip file. They're normally in a .jar file. You most likely downloaded these mods from unofficial sources. Also, modpack.jar should be a renamed forge .jar file, not a .jar containing a folder called "modpack" like you have.

Hello, Rektgaming.

The reason why some of the mods are in a .zip when they are usually in a jar file is from the second post in this thread.

I have decided to start over with this modpack, so now I'm using 1.7.10 forge (with mods that are both in zip and jar files) from my own Minecraft directory, which I know has conflicting ID's. Now the game loads in Vanilla. Any help?
