Minecraft Forums

I have been having consisting problems trying to get the Imibis's Microblocks mod for minecraft 1.7.2 (on a Mac). When i download it from its 9minecraft post, it downloads as a .jar file. Keep in mind that I already have forge 1.7.2 installed and a couple other mods: Mo' Creatures and Carpenter's Blocks, which should not affect the microblocks mod. I did make sure that the microblocks mod was the 1.7.2 version, and I tried to execute the .jar file but only came up as an error. I know that it says I need the Imibis's Core mod and to put it into the mods folder, but it also says to put the Imibis's Microblocks mod into the "coremods" folder, but in 1.7 +, there is no coremods folder... This is where I am stuck, does ANYONE know what I can do to fix this?

In short. Get the mod from it's official source, and follow it's official installation instructions.

Except there is says to put the microblocks mod into the cormods folder, which there isn't one of.

Download links are up to date so use them. And install Microblocks like any other recent Forge mod (everything goes to to "mods").

That is what I have been trying to do. I was putting the microblocks mod into the mods folder and the core mod that goes with Imibis's mods. But every time I try to launch minecraft like that, it goes to the screen where you press the play button immediately. I also tried puting them in the Minecraft.jar and one in each, but nothing has been working...

Can you post your console log. From when the files are in mods folder and the game fails to start.

From the point to me pressing the play button to the point at which I get the log.

This is with putting "immibis-core-58.1.4.jar" and "immibis-microblocks-58.1.5.jar" in the mods folder.

You need to install Java 7. Then you'll have to configure Minecraft Launcher to use that Java 7.

Once I get Java 7, how do i configure my Minecraft Launcher to use it?
