I don't know what went wrong

[CHA]

Hi

 

I tried to run forge after downloading a clean minecraft client

 

This is my first time installing a mod so I really don't know what this crash report means

 

I moved the files from the most recent Forge client (4.0.0) into my minecraft.jar, deleted META.INF then compressed it as minecraft.jar

 

After running through the launcher, it crashed and gave this error report

 

Any support or help would be appreciated

 

Error report is in spoiler tag

If anyone else had a similar problem, I solved this and it works now

 

The issue was with Archive Utility creating an invalid .jar, so I used a different archiving program (The Unarchiver)
