Export 32 bit Normal maps from zbrush 4 r6?

Hi guys!
I know this is a newbie question, but is there a way to export 32 bit Normal maps using multi map exporter in Zbrush 4 r6?
I accomplished that in the past by using ZMapper, but it is no longer available, and i can’t find a button in the multi map UI to do that.

Thanks very much in advanced for the possible answer.
