There are other ways of doing this but your current approach covers more ground than they could. For example, you could use RegistrySearch to detect other installers (presumably!) and use a launch condition to tell the user to uninstall other versions. Or you could use a FileSearch that ran in the execute sequence but that would delay feedback to the user -- ideally, you want to tell them as soon as they select a directory. -- sig://boB http://bobs.org ------------------------------------------------------------------------- Using Tomcat but need to do more?
