Error: Invalid or corrupt jarfile

[iakosv]

Hi,

 

I have been trying to download FML Forge but when I try to use the installer it comes up with a pop-up that says Error: invalid or corrupt jarfile.

 

I have the latest version of Java as far as I can tell (Version 8 Update 211 build 1.8.0_211-b12).

 

I have tried with both MC 1.12.2 14.23.5.2768 and 1.8-8.0.127.1103 but both get the same message.

 

I have been Googling the issue and there was one similar thread on here back from 2013 which suggested the approach used in this video (https://www.youtube.com/watch?v=j6uMF-PjGT4) but I got the same message.

 

The log says this:

It looks something like this:

 

 

I don't know very much about programming and apologies if I've made a mistake - I did read the rules so have tried to make a correct post.

 

Thank you.

Firefox and a 0 kB Forge installer, Firefox blocked the download.

Go to Firefox’s download manager to recover the file and try again.
