This is the x32 Octane build for the last 11.6 pre-release, LW build 2708 ... please try this x32 version with your system, you only need to repleace the plugin file you have with this new x32 one (you can rename it if you want to overwrite your LWOctane_x32.p file and simple start LW again)

As you know 11.6 is in beta stage, and there are changes in each build that breaks the Octane plugin, so perhaps for the next LW11.6 release or for the final 11.6 I am going to need to update the plugin again.
