I know whether it's on Windows or Linux, Java is Java is Java, well, that's how it's supposed to be, but practical experience in the past shows it's not always the case. I have tired renaming -zip to .jar, but Minecraft still crashes regardless. It seems strange to me that most jar files work, but not a single zip filed mod works... Thanks for your help, but I guess we can leave this one as unsolvable - my boy now knows, if the download file is zip, he won't bother with it. Quicky quesion, off-topic: I've clicked "Applaud" several times for folk, but in the "Thanks given/received" bit, it stills shows "0"."

Thanks for the clarity there. He now has several mods installed and running. One thing we have noticed is that all the mods that work on his installation are java archives (.jar). All the mods he has tried that are zip archives don't work - not a single one, despite most having the same version number as the forge installation. Could this be something to do with the laptop running Linux as opposed to Windows?

Thanks yarrmateys. Looking at the actual pages for the mods downloads, they state the version of Minecraft needed. In most cases it says 1.6. I will look again at those pages. I did look for animation.api but couldn't find it and assumed it was part of the Forge package. I guess i was wrong on that note. Happily though, we tried a couple more mods and they worked first time. interestingly, the two mods that work are java files where-as the ones that don't work are zip files. It means my boy has something working, and keeps the pressure of me! Thanks gents!

Aha, thanks, I hadn't realised that the mcblah.blah.blah was the version of Minecraft it worked with and that it was so version specific. I'll check more carefully next time. Though not all mods are numbered so helpfully.

If this is in the wrong place, sorry, but I'm not sure where to ask for this... I know almost nothing about Minecraft, except what it is. My little boy wanted the Mutant creatures mod for his Minecraft. I read through the Minecraft Wikis and what-not and found I needed the Forge package. I found and ran forge-1.6.4-9.11.1.965-installer.jar. I got he message that it had been installed OK. Running Minecraft and selecting the Forge profile, it runs OK. I then downloaded Mutant_Creatures_v1.3.6_mc1.6.2(1).zip, made the folder .minecraft/mods, and copied it there. However, running Minecraft with the Forge profile, it crashes and gives the following error report: ---- Minecraft Crash Report ---- // I blame Dinnerbone.
