Does anyone else get the problem SEVERE: Unable to launch when trying to load this or other FTB 1.6.4 packs
IIRC you need 64bit java(requiring a 64bit OS), and atleast 2gb of memory alloted to minecraft
Don't quote me, but I don't think 64-bit java is specifically required to run any FTB pack, as that would exclude most older PCs. It may, in fact, be implied, by the amount of recommended RAM if the modpack has one...as I recall 32-bit Windows having a RAM cap [then amount of which escapes me ~2.4G?].
@Roxlvox : If your problem is what I think it is, you need to be using Java7 (32/64-bit depends on your hardware) vice Java8. FTB Launcher has issues with Java8. You don't need to uninstall Java8, just install Java7 and specifically tell FTB to use Java7. If you already are using Java7, then you'd need to post the server.log via spoiler/pastebin for more assistance.
And is this a troll or what? Free Laser Assembly Program, combined with Drill Assembly Program [cost of 8 Emeralds + Diamond] results in being able to process a total of 1 items [Compressed Iron Block -> 8 Adv Pressure Tubes]? If this is working as intended, all this does is fuel my dislike of PC and I call Shenanigans.
