How to Update offline ai2 v185a to v186a ?

Where did you get your offline version? If you got it in another place you should ask the developer who made it.

So you got your previous version from there? Then you have to put the newer version along side it. As far as i know you can not update to get the new parts merged with the old version. If you try i guess it can only give you trouble.
