For Java I would suggest checking the registry key "HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion". I have had trouble checking the upgradecode as they sometimes install side-by-side.
Also, don't forget that this is an install for 32 bit and 64 bit and therefore different registry keys for each version.

Subject: Re: [WiX-users] Java check As this is a pre-requisite I'm glad you're plan is to block the install from the MSI with a meaningful error message if Java isn't installed. That is definitely the right thing to do. Fortunately the Java installer is MSI based (or at least the one installed on my PC is), so detecting it from your WIX MSI is going to be fairly easy. One way to search for it could be to use a ComponentSearch. But better I think, is to use FindRelatedProducts and search for Java's upgrade code (I assume this would only change when a new major version comes out, like from 1.5 to 1.6). Something like: <Upgrade Id="{JAVA'S-UPGRADE-CODE}" <Property Id="JAVAISINSTALLED" Value="1" /> </Upgrade> <Condition Message="Java isn't installed. Get it from Oracle and try again">NOT JAVAISINSTALLED</Condition> (Don't forget to schedule FindRelatedProducts in your InstallExecute and InstallUI sequences if you haven't already) -Thom -----Original Message----- From: Leonidas Spyropoulos [mailto:leonidas.spyropou...@formicary.net] Sent: 12 January 2011 13:11 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Java check Hey all, Is there a way to check if Java is installed while installation? Also what kind of versions and if not is it possible to ask the user to download & install?
