Technic Platform not launching Tekkit Legends

[celious21]

Hello,

I have a problem. I installed technic platform and latest update of Java(Version 8 Update 281, the 64bit version) and every time I try to play Tekkit Legends it displays this in the console:

I have tried deleting .technic and installing the platform again but it does not work. The only thing that worked was installing the 32bit version of Java, but only works for Singleplayer and crashes when I try to connect to a server as it only has 1Gb of ram allocated. Does anyone know how to make it launch on 64bit?
