The one error I understand is that the mod has "no version" to it, I assume that's the mod's version not a version of Minecraft required for the mod... (although I'm running 1.7.10 minecraft and that's supposedly the MCHeli required version I have...)
Thoughts/advice greatly appreciated. I've done some basic web searching but no real luck.
I had already read through all the MultiMC instructions I could find, (and google searching on the topic gets a LOT of off-topic noise).
I read some of the MCHeli instructions but I did not see how they meshed with using MultiMC... (do I set up an instance, then put all the MCHeli files in that instance directory? would that screw things up
Knowing there are loader mods and jar mods is a great bit of advice that was not readily apparent in the MultiMC documentation (which is sparse on many things as best... particular to a neophyte mod-user like myself) On to the fun:
OK, this time I set things up (vanilla 1.7.10) and newest appropriate Forge. I then installed the MCHeli zip file through clicking through the Loader Mods option under edit instance....
Still no luck. still getting a -1 error at the end...

OK, create an instance in MultiMC... (I think I need forge, I'll check on that...)
Then go to that instance's folder and much around with it directly as MCHeli wants... cool.
Thanks for the help, wasn't sure if I mucked around with a particular instance (mods and such) and not through the MultiMC interface if that might mess up the MultiMC loading features...
(I've found the MultiMC documentation to be a bit light, thus my need for more specific information.... not a surprising thing since MultiMC is a labor of people donating their time. I'm glad the program's there - maybe I didn't find the right manual, but after reading what I could find I still had big gaps of understanding how the guts of the the interface was providing.... ie. Telling someone to read up on the MultiMC instructions might not be the best default... I did mention I read up on what I could via web searches... that would include as much as I could find on MultiMC...)
I got MultiMC up and running to be able to run various mods for my young boys... I've done a few basic mods with no issues.
They want to try the helicopter mod and Minecraft crashes before it gets to the home screen.
1) Create vanilla 1.7.10 minecraft instance (runs fine)
2) Duplicate and add in most currrent 1.7.10 forge (runs fine)
3) Duplicate and add in MC1.7.10_mcheli_0.10.5 (a zipped file I keep in my MultiMC mod folder)
It loads up apparently but then crashes before I get to the minecraft home window...

The one error I understand is that the mod has "no version" to it, I assume that's the mod's version not a version of Minecraft required for the mod... (although I'm running 1.7.10 minecraft and that's supposedly the MCHeli required version I have...)
Thoughts/advice greatly appreciated. I've done some basic web searching but no real luck.
Thanks for the tip.
I had already read through all the MultiMC instructions I could find, (and google searching on the topic gets a LOT of off-topic noise).
I read some of the MCHeli instructions but I did not see how they meshed with using MultiMC... (do I set up an instance, then put all the MCHeli files in that instance directory? would that screw things up
Knowing there are loader mods and jar mods is a great bit of advice that was not readily apparent in the MultiMC documentation (which is sparse on many things as best... particular to a neophyte mod-user like myself) On to the fun:
OK, this time I set things up (vanilla 1.7.10) and newest appropriate Forge. I then installed the MCHeli zip file through clicking through the Loader Mods option under edit instance....
Still no luck. still getting a -1 error at the end...

OK, create an instance in MultiMC... (I think I need forge, I'll check on that...)
Then go to that instance's folder and much around with it directly as MCHeli wants... cool.
Thanks for the help, wasn't sure if I mucked around with a particular instance (mods and such) and not through the MultiMC interface if that might mess up the MultiMC loading features...
(I've found the MultiMC documentation to be a bit light, thus my need for more specific information.... not a surprising thing since MultiMC is a labor of people donating their time. I'm glad the program's there - maybe I didn't find the right manual, but after reading what I could find I still had big gaps of understanding how the guts of the the interface was providing.... ie. Telling someone to read up on the MultiMC instructions might not be the best default... I did mention I read up on what I could via web searches... that would include as much as I could find on MultiMC...)
That did the trick!
Thanks again.
(So the "loader mods" is an informational thing, not a tool to use to put things in there?)
