OVO Photo Viewer Software 2.3C

My mother-in-law gave my father-in-law an OVO photo viewer key chain as a gift but the software for it comes on a mini CD, which can't be inserted into our MacBooks and therefore we need to find a site on the Web to d/l the s/w from. Does anyone know where I can get this software or could email to me?

I d/l'd the newer rev of the software but it does not seem to recognize the device when we plug in the USB leadinng me to believe that, amazingly, the s/w is not backwards compatible.

Please let me know if you can help.

Thank you.
