Error 500 installing SuiteCRM under Winhost

Hi, I am new in SuiteCRM.

At the moment I have my website running on Winhost.com (Windows /IIS hosting).

So, I tried to install SuiteCRM under subdomain but the error message is:

HTTP ERROR 500

I installed the same files on Apache/Windows in a local computer and everytihing is Ok.

What could be missing? How can I track the error?

Thanks in advance.

Regards

Juan
