I cannot get rid of this: Addon CA_BAF requires version 1.56 of application. in ARMA 2 & OA - TROUBLESHOOTING Posted October 7, 2012 · Edited October 8, 2012 by CyOp I have had this for a long time and finally decided to post. Yes, I have installed all the latest patches, etc. NOTE: I only get the pop-up when I launch from the Arma 2 shortcut. Nothing special in it but -nosplash. I have: (Arma 2 ... 1.11) Arma 2 CO ... 1.62 BAF PMC ACR TIA EDIT: Yeah, I thought it was unusual.
