      Server Move   09/13/2018

      I (Dries007) have recently taken over as main developer and server admin. This involved moving servers to reduce cost. It's likely there will be some more downtime in the future but most  things should be sorted by now. This forum is in dire need of replacement as the software is quite old and can't be easily updated. If you wish to discuss or stay updated, join our discord: The forum will remain available to read, but will be locked in the future, when a new system is setup. The forum and wiki are now ad free. If you'd like to contribute to keeping it that way, you can do so via paypal or patreon.

      ATTENTION Forum Database Breach   03/04/2019

      There has been a breach of our database. Please make sure you change your password (use a password manager, like Lastpass).
      If you used this password anywhere else, change that too! The passwords themselves are stored hashed, but may old accounts still had old, insecure (by today's standards) hashes from back when they where created. This means they can be "cracked" more easily. Other leaked information includes: email, IP, account name.
      I'm trying my best to find out more and keep everyone up to date. Discord ( is the best option for up to date news and questions. I'm sorry for this, but the damage has been done. All I can do is try to make sure it doesn't happen again.

[Solved] Forge MC v.1.6.4 won't load past launcher

3 posts in this topic

I am unable to follow the very simple video on how to install terrafirmacraft properly due to the fact that forge simply will NOT launch 1.6.4


Is all I get from the launcher being left open. There are no crash reports at all and I have even attempted to do this with a fresh install of the .minecraft folder.


Started fresh MC - Auto updates to 1.8 (download and runs fine)

Close game and back to launcher

Set to 1.6.4 mc and run (downloads and launches to main MC menu fine)

Download forge (install to default directory with everything else MC related)

close launcher and re-open 

Changed profile to forge and attempted to play (Game client never opens)


I am able to download the latest version of forge and load it properly to the main client. Obviously I do not need that version so I did not re-install it when I cleaned out my .minecraft folder for this fresh install.


Any suggestions?

What version of java are you using?


Minecraft/Forge 1.6.4 is not compatible with Java 8. You need to downgrade to Java 7.

Ah thanks for that I am on java 8 due to problems I was having with MC 1.8.


I will downgrade then! That is probably my issues!


You have to fully uninstall Java 1.8 and restart for it to work. Simply disabling java version 1.8 will not allow it to work. Just a heads up



also sorry I could not find a topic related to this that pointed this issue out.
