[maxmsp] .mxf Application Mac to PC

I am creating a .mxf Jitter Application on my OSX Intel MAC.  I am trying to open and play this application on my PC laptop.

When I try to open the file on my laptop, my computer won't automatically open it and wants me to "choose the application which created it"---impossible because I don't have MAX/MSP on my PC.

Shouldn't I be able to open this .mxf file on my PC?  Do I need to export it differently or open it differently?

Thanks!
