Much as I don't like to put people off MSI, would something like Java Web Start serve you better ?
We test for JRE installations in our product using the upgrade code/product code. This is easy to test for if you're only interested in a specific JRE/JDK version. You could do this with the upgrade table without resorting to custom actions. You'd have to download all the compatible versions and pull out the product and upgrade codes unless Oracle have a KB article for them. Just be careful of the upgrade/parallel installation option that modifies the product code. -----Original Message----- From: Mike Rerick [mailto:mrer...@iwsinc.com] Sent: 13 January 2012 15:38 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Writing JDK version verification code, and Wix debugging tip The app being installed is a Java app. Can't run it without Java being installed. If Java isn't installed, the installer needs to quit with an error msg to the user.
