Minecraft Runtime Environment cannot start

  • 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.

Title:
Minecraft Runtime Environment cannot start
Launcher Version:
Not sure, other than newest version of Curse
Modpack:
Any
Modpack Version:
Any
Log Link:
Details of the issue:
Sorry for the lack of details, but whenever I launch a pack on the Curse launcher it downloads the runtime and spends ages setting it up before crashing and saying that the Runtime Environment cannot start, likely due to corruption. I have tried reinstalling the modpacks but it still doesn't work.

Delete the folder D:/19chickens's Stuff/Games/Minecraft should make Curse re-download the required Minecraft files.
