Why not check it when the application starts up ? It'll be easier to code and the user has the option of installing Java after your product instead of forcing it to be done beforehand.

My product requires JDK 1.6 installation, and I'm trying to come up with Wix code to verify the system has JDK 1.5 installed before proceeding installation of my product. I thought this would work: <Property Id="JDKVER"> <RegistrySearch Id="NetFramework20" Root="HKLM" Key="SOFTWARE\JavaSoft\Java Development Kit" Name="CurrentVersion" Type="raw" /> </Property> <Condition Message="This application requires Java Developer Kit 1.5 (or higher)."> <![CDATA[Installed OR (JDKVER << "1.5" )]]> <!-- test with 1.6, 1.7, 1.8, etc. will be added later. --> </Condition> But this didn't work. Even if JDK 1.5 is installed, this message is displayed. Anybody has experience doing JDK version check? In an attempt to debug this, I wanted to display the value of property "JDKVER", and inserted this code. This is a modified version of the code I've found in the Internet: <CustomAction Id="ShowProperty" Script="vbscript" Execute="immediate"> <![CDATA[ MsgBox "JDKVER =" + Session.Property("JDKVER") ]]> </CustomAction> <InstallExecuteSequence> <Custom Action="ShowProperty" Before="InstallFinalize">True</Custom> <!-- "Not Installed" didn't work either. --> </InstallExecuteSequence> But no popup came out. What am I doing wrong here? Thank you in advance. T.
