Not knowing what operating system you are running I would highly recommend upgrading to xampp 1.8.2 on both pc's for consistency, functionality and security reasons -> http://sourceforge.net/projects/xampp/f ... ows/1.8.2/
Xampp has copies of all its historical releases -> http://sourceforge.net/projects/xampp/f ... 20Windows/
Your php version does not match any release I can see from Xampp (might of missed it) referencing -> http://en.wikipedia.org/wiki/XAMPP
For future reference it's always handy to keep the original download file(s) you used in case something goes wrong (changed settings, unexpected error/crash, just need a fresh start).
Can you please explain why you can't upgrade your current setup to a later version of Xampp / why it has to have those specific versions? (XAMPP 1.8.2 supports Windows XP or 2003)
