Mantis Bug Tracker - Forums

I've download Mantis 1.1.2
IIS 5.1+php5.2.6+mySql 5.1.11
but when I execute mantis/admin/install.php

Checking PHP support for database type:
BAD
database is not supported by PHP. Check that it has been compiled into your server.

please give some help.

Looks like you didn't install PHP properly. Lets start with which windows binary you downloaded.....the insaller package, or zip package?
