Is BI Needed to Install EB

I have RTW patchs up to 1.5, but I do not have the Barbarian Invasion extention. Is BI needed to intall EB?

No.

Some EB players use the BI or Alex EXE file to play EB, but that is entirely optional, and also unsupported by the Dev Team.

RTW is all you need to play EB.

Thanks
