I want to find out if Winzip is installed on a client's machine. I know I don't always install programs in their "prefered" directories so how can I really find out if .zip is associated with winzip. I found an API function in Win API section but the function requires an actual zip file to exist. The function also returned the path in DOS format ( c:\progra~1\winzip8 ). There must be an easier way. I'm here using Winzip as an example but I also want to know if .doc is Word or WordPerfect etc

Thanks in advance
