Standalone Player - will not work on my macbook

Any help will be much appreciated.

I produce a 3 minute standalone played slide show on my mac tower. The standalone player slide show will play and work on my mac tower.
I then try to play it on my macbook, my macbook is old about 2007 running Mac OS X 10.7.5 she is a 2.33 GHz Intel Core 2 Duo with 3 GB of memorary. My macbook pro will play standalone player slide shows !!

I only gave fotomagico installed on my mac tower.

Does anyone out there know why please ?

Thank you, edwin
