problem with php5_module

[edumax]

I developed my first website using your framework, I developed on my server with xampp installed and it works great.
But in my hosting. I have error message "500 internal server error". Then say me the php5_module is not installed in his server.
The hosting technical support informed me that the server does not support the php5_module. How to fix this?.
i appreciate any comments.
Regards,
