wix Launch Condition for isapi&cgi restrictions

My program 开发者_开发知识库needs isapi&cgi restrictions are installed in iis. I want a wix launch condition for isapi&cgi restrictions are installed or not. Any help would be great. Thanks in advance.

A solution is to write a custom action which detects if these restrictions are installed or not. Based on the result it can set an installer property which can be used as a launch condition.

You can find a custom action tutorial here: http://www.codeproject.com/KB/install/msicustomaction.aspx

The custom action should be scheduled before LaunchConditions action and it should be Immediate.
