  • Tech Support section is for getting help with FTB related problems. If there's a repeatable issue that can be labeled as a bug, then please use the issue tracker for the pack or the app at GitHub issue trackers - If there's no repository for a pack that means that the pack is old and/or will not be updated. Bugs for older packs will not be fixed, unless they are critical.

Did you ignore this warning message without fixing the problem: "[ERROR] MainHelpers.printInfo:63: 32-bit Java in 64-bit operating system. 64-bit Java is required for most mod packs. If you have issues, please try the FTB Lite 2 pack."? Fix that, increase memory allocation to 2-4 GB and try again
