unable to run 1.6.4


Recommended Posts

I have been trying to download and run any of the 1.6.4 versions with no luck. I get the menu to select client/server install and I pick server point it to an empty folder it downloads libraries and the server jar so then I make a server start bat file and oint it to the universal forge file, click on the bat get a quick pop up of text with about 6 lines and an error message I can't read and then back to desktop.


Try exactly the same steps with 1.6.2 build 871 and instant working server. Anyone hear of this yet?

We appear to be missing one or more essential library files.

You will need to add them to your server before FML and Forge will run successfu
