EDU for EB with BI's exe

[Sarkiss]

I have a question. I installed RTW and patched it to 1.5

I then installed barbarian invasion. What do I next to play EB with Barbarian invasion? Can I install EB or do I need any patches for BI?

yes, you need 1.6 patch for BI.
once you done that just go here - https://forums.totalwar.org/vb/showthread.php?t=88717 and get this installer. it is awesome, it'll do everything for you including adding BI's formations. im currently playing as Carthage with it and Romans just took Korsica (naval attack) so Punic war begun! it'd never happen with 1.5.

EDIT: after you patched BI to 1.6, you obviously need to install latest EB first and then the installer that i linked.
good luck
