    You are missing a component of Redpower (Logic). It is needed for Array.

    What exactly does that mean? What component exactly is missing, do you know? All the seven Redpower zips are in the mod folder.


    Thanks

    Just realized I had the wrong RedPower files in there, but now I have the correct ones. It still doesn't run, but the console reports a ID conflict that I fixed and removed the error for, but it STILL doesn't run. The new log is below, note that when I resolve the ID 150 conflict, the error simply goes away from the log (the rest remain). Also I should mention I got IC2 working alongside with BC, so now RedPower is the only issue.


    I'm getting the same 'Slot 150 is already occupied by eloraam.machine.BlockMachine@10db5b3f when adding buildcraft.factory.BlockMiningWell@31438dbe' error that Subrose reported in his follow-up post, while combining IC2 1.71, Buildcraft 2.2.12 and RedPower 2.0 PR4d). In my case, it's a client side only installation, and I've successfully combined all three mods in the past prior to 1.71.


    Renaming the RP zips made no difference.


    Edit: I ended up solving the problem by poking around and deleting both the buidlcraft and redpower folders in the minecraft root and all the associated .cfg (and mod_*.cfg) files with it that I could find. Running it again regenerated them and it worked eventually.
