I've many trouble installing the tools on my MacPro with the Adobe CS5 Master Collection.
I've downloaded the correct dmg files and I've install them in correct order (first Folio Producer and then the Folio Builder).
But when I open the Folio Builder window, the window itself show me message that is necessary to update the tools.
Even after updating doesn't change the message.
It's possible that this tools are incompatible with indesign Master Collection version?
this are the links I used from Adobe site
