I use drop box and it works just fine. It might be because I made a dropbox a while ago and still have a public folder.

Try wiping your client side and start with a fresh download of the modpack. Sometimes it doesn't overwrite the files properly.

You might be able to if it has an option for the direct download of files. I don't know though for sure. You would have to consult google for that information.

If you don't need any configs you can just leave the folder empty. Are you referring to the mod tab in the minecraft home screen? That will only show if FML is properly installed (which the guide shows you how to do). Mod edit: Learn to use the edit button.

I just went through your modpack and I can't seem to find any issues. The only thing I might be able to think of is possibly all the configs are messing things up somewhere along the line. Maybe try isolating the problem by removing the configs and try running again.

Can you link the direct download link and not the platform link?

You need a dropbox public folder in order to distribute the pack. I don't know how to get one if it already doesn't have it. Check the dropbox website. That's where the modpack needs to go in order to get a public link though.

Are you placing that link into Platform? You need to place the automatic download link into platform. This can only be obtained by placing the .zip file in the "Public" folder on your drop box. One you have that, you will get a "Public Key" by right clicking I believe. (IE:https://dl.dropbox.com/u/67646975/mods.zip). This is the only way that Platform will download your pack. Edit: Otherwise, from what I can tell, your modpack looks to be correctly setup.

I'll add one now haha. That seems to be 90% of the things said in this section.

Did you check all the possible bits of error (like what milk1432 had)? I can't really give you more information without actually seeing the pack itself.

No problem. Sometimes we all need a second eye (or I guess a third unless you're a Cyclops). I know when I was trying to get it to work, I completely deleted the "bin" file from my client side and made it start all over again downloading everything again. The update system is weird and if it senses that the name already exists, it does not overwrite the file (especially if it is the same version). Try deleting the bin files and re-downloading the pack. That should work.

For sure it will work when you manually place it in. The idea is to get the platform to do that for you and your players. Also, I just downloaded your modpack from the file and in the Bin, your "modpack.jar" is actually saved as "modpack.jar.zip". Try removing the zip file attachment and changing the actual file (not just the name) for modpack.jar.

More information is needed before you will get any help.

Make sure that you are compressing the items in the bin folder to a .jar file and not a .rar file. That can cause issues.

I edited the post to properly show how to make the modpack.jar file. Hopefully this eases confusion. I also added a disclaimer at the bottom about distributing the minecraft.jar file. Hopefully this is correct. Thanks for the help. I just felt like this section needed a comprehensive view on how to properly do this. I wrote the guide as I figured it out how to do this myself.

Ok, Thanks for the input. I was misled. There wasn't any other information on how to properly do this. So, in order properly do this, you create a modpack.jar that ONLY includes the FML files and Jar Mods that require themselves to be in the mincecaft.jar?

Maybe this might help your problems. I just made a guide on how to compile a modpack. Hopefully it might contain a step or two that you missed.

Here you go! Happy crafting.

For all of you out there that are/were having the same troubles as me putting together a modpack, I am making this guide for you. Please feel free to message me/post revisions below. Without any further ado, here we go. Step 1: Find your mods Every mod pack needs mods. So go find some that you want! For this example we will use Industrial craft 2 and Buildcraft. Once you have downloaded the ZIP files that you want, we will create a quick file structure to organize how the downloader reads our mods. Step 2: Create some structure You will want to create the following files in an empty folder (which we will entitle Custom Modpack). bin - where we will place the .jar files so that it loads your modpack not as vanilla. config - where you can set certain configurations for people on your server coremods - the place where coremods go mods -the place where your individual mods go. (For some reason, screen shots and I are not getting along so I will just link all the pictures) Sample modpack folder Step 3: Create the modpack.jar file Go grab a fresh copy of the forge mod loader (FML) from their website. Extract all of the .class files in the FML file and place them in the bin folder. From here, select all of the files in the folder you are in (control-a), right click, and compress the files. Photo Rename the resulting "Archive.zip" file to "modpack.jar". If prompted whether or not you really want to do this, show it who's boss and do it anyways. Photo **Caution: If you mess this up, when you download the pack, it will not change the .jar and simply run as vanilla. If after attempting to fix with an updated file, pack still launches at vanilla, you must go into the local client side files and delete the modpack.jar file. When you download the pack again it should launch with FML.** **Attention WinRar Users: make sure that when you compile the .class files from FML into the "Archive.zip" folder and change it into "modpack.jar" you ensure that the "modpack.jar" is a .jar file and not a .rar file.** **DO NOT distribute the actual minecraft.jar in your modpack (similar to how users sometimes mod their client). The modpack.jar file should contain ONLY the FML and other .jar files that would normally be required in the minecraft.jar. Distributing the minecraft.jar file is PIRACY. ** Step 4: Add your mods To add your mods (in this case buildcraft and industrial craft) simply drag them into the "mods" folder which you created. Straight up. Step 5: Compile the modpack Almost there! Now just select the four folder which we created (bin, mods, coremods, config), right click, and compress them into a .zip file. Photo Rename the resulting Archive.zip file to whatever you would like. For our case, we will name it mods.zip. Photo Step 6: Host your .zip file somewhere. There are tons of different options for this. Personally I use drop box but the options are nearly infinite. Upload your .zip file somewhere on the internet, paste the link into your platform panel, and publish your mod pack. Step 7: Enjoy some modded minecraft. If you did all of the above steps correctly, you should be able to load minecraft up with all of the mods. Step 8: Applying this to your server When launching these for a server, simply follow the instructions on the FML website for installation of FML on a server. Once it is installed, place the mods/coremods/config you have already set up client side into the mods/coremods/config directory created when running your server with FML on it. Common Problems and Solutions: My mod pack loadz as vanilla. Y UU NO WORK! (end caps lock) Chances are your "modpack.jar" file is actually either "modpack.jar.zip" or "modpack.rar" please ensure that your file format is properly changed. A simple google search will tell you how to how to unhide file extensions for whatever program you are using allowing you to properly change the name. Didn't work. Please include more information as to what didn't work. Download files and error reports are VERY helpful. Platform isn't downloading the pack correctly/at all. Please ensure that you are using the correct URL in platform. For dropbox users, this is the "Public Key" or after right clicking, the "Copy link". For MediaFire users, right click the green "Download Here" box and select "Copy Link". Please make sure you are posting the direct link to the file download and not just the website URL link where the file is. "Insert Problem Here" Please read through the previous pages to see if your problem has not already been discussed. I can't manually go through every persons file and sift out what it wrong. Also, if for some reason you cannot get your modpack to work or are having trouble with my guide feel free to read IceWolf's guide on Building Your Own Modpack. I hope this guide has aided you in creating a functioning modpack that you can play with. I wish you all the best of luck with your modding experience.

I'll post a (hopefully) complete guide up soon. Just trying to actually get the files working myself .

Would you mind posting steps to how you resolved this problem? Was it simply that the modpack.jar was actually a .rar file?

All, So currently I am making the transition from a structured modpack (mindcrack) to a custom modpack and adventure map. I have a list of coremods and mods put together that I want on the server zipped up and ready to go. They download just fine and show up in the client folders where they should be. However, upon logging in, none of these show up. Upon further research, I cannot seem to find forge mod loader or a modified minecraft.jar in the server bin file.Thinking I was sneaky, I tried to also create a new Bin file and zip it up with the other ones. However, upon clearing the cache and re-downloading the pack, nothing in the Bin folder changed. I guess my question boils down to this, how do I include the forge mod loader in the pack (if I even need to at all and I just can't figure it out). Any help is appreciated. Let me know if you need any more informations.
