  • My game is crashing, lagging, or never fully loads! - Try allocating more memory to your launcher, around 2-4GB. A how-to guide on adding more memory is located here.
  • I only can select up to 1GB of memory! - Please install a 64-bit version of Java 8. (Windows/OS X download)
  • My modpack fails during the download/installation! - First try restarting your PC and internet. If those fail, try disabling any Anti-Virus or Firewall as they may be blocking the installation due to false positives. If the issue still persists, please reinstall the Technic Launcher.
  • My game is still having issues and none of the other methods fix it! - Please locate the crash report file, create a ticket on our Discord, and send us the crash report. A how-to guide on crash reports is located here.
