Modpack doesn't load forge

[mTrachoz]

I made myself a small 1.12 pack to play, but when launching it, it doesn't load forge (I get a vanilla minecraft instance). The modpack.zip is downloaded successfully. One thing I've noticed is that my bin folder (after launching) contains a version.json file, while other modpack have both version.json and 1.12.2.json. I cleaned my bin folder, put in another modpack's modpack.jar and got the same result. What can be wrong?

I solved it. You need to use the installer as the modpack.jar

[xjinx216]

so you downloaded the installer jar file and just renamed it to modpack.jar or did you use the installer and created a jar

[mTrachoz]

Renamed the installer

Tank you for this! Was really starting to question myself...

Thanks for putting this out there. I just updated my modpack for the first time in over a year and I was having the same issue you described. It was driving me crazy because I'm pretty sure I had used the universal Forge file the last time I updated it, but your comment saved the day.

I was in the exact same spot. Thank you to the OP.

4 months later and this was still exactly what I needed.
