That's how it is but forge is not installed then. And since forge doesn't install nothing installs and it stays vanilla MC. I was just testing and when I added the modpack.jar files to minecraft.jar it does work, but I know that's not how it's suppose to work.

The 4 folders are not in another folder they are simply in the .zip. It looks like this: custom.zip bin (folder) config (folder) coremods (folder) mods (folder) And NOT like this. custom.zip custom (folder) bin (folder) config (folder) coremods (folder) mods (folder) Edit: After trying with forge 534 it now downloads all the files and has them in the custom mod pack folder (coremods now has the core mods, bin has modpack.jar) But modpack.jar still isn't installing into minecraft.jar automatically so it still starts up as vanilla MC until I do that.

After lots of hard work making a custom mod pack for a private server I uploaded it to my dropbox, directed technicpack.net where to get it, tried to install it, and it doesn't work. It shows that it's download the .zip file and when it finishes, it launches minecraft but it's only vanilla MC. When I look in the folder for the modpack the coremod and config folders are empty, the mods folder doesn't exist, and there is no modpack.jar inside the bin folder. The .zip file has the 4 folders (bin,config,coremods,mods) and in the bin is the modpack.jar with forge inside. Also If I copy and paste in the 4 folders from the zip into the custom pack folder, it still runs as normal vanilla MC. It only works correctly with forge and all the mods running if I copy in everything from the modpack.jar into minecraft.jar inside the .bin folder and then run the pack. In short: the launchers isn't downloading and installing the custom zip file and modpack.jar isn't installing into minecraft.jar.
