Cool, I think we'll go with this approach. Comparing what's in my registry with what seems to be going on below and since I have no experience with registry searches or ExePackages, I have some questions:
1) The Java version seems to be the value HKLM\SOFTWARE\JavaSoft\Java Runtime Environment\Java7FamilyVersion, which seems to be what Java7FamilyVersion fetches. However, why doesn't WiX ever compare Java7FamilyVersion with what's supposed to be the correct value (i.e. 1.7.0_21)? 2) Since Java7FamilyVersion already seems to get the version, what's the point of doing the second registry search (i.e. "JavaProductVersion")? 3) In my registry, the JavaProductVersion looks like it would fetch "7.0.210", which would always result in the condition "JavaProductVersion >= v7.0.210" being FALSE, no? (Since "7.0.210" != "v7.0.210") 4) What is/should be "[WixBundleLog_Java7Runtime]"?
