<div>For Raptor, I ended up with a single MSI for 32 and 64 bit, and to figure out JAVA_HOME I’ve ended up looking in the registry and figuring it out rather that using the system provided one, like so:</div>
<div><br>
</div>
<div><Property Id='JAVA_VERSION'><br>
<span class="Apple-tab-span" style="white-space:pre"></span><RegistrySearch Id='JavaVersionSearch' Root='HKLM' Key='SOFTWARE\JavaSoft\Java Runtime Environment' Name='CurrentVersion' Type='raw' /><br>
</Property><br>
<Property Id='JAVA_HOME'><br>
<span class="Apple-tab-span" style="white-space:pre"></span><RegistrySearch Id='JavaHomeSearch' Root='HKLM' Key='SOFTWARE\JavaSoft\Java Runtime Environment\[JAVA_VERSION]' Name='JavaHome' Type='raw' /><br>
</Property></div>
<div><br>
</div>
<div>Seems to work for me when I’ve tested on 32 and 64 bit, but I’d need to to a lot more testing (with 32/64 bit JREs on 64 bit windows) to be comfortable that that was a solution that actually worked in all scenarios. I hacked that together as a temporary
thing, and so far haven’t had any reports about it not working for anyone, so haven’t had to fix a better solution yet. But whether because it works, or because none has yet deployed it in a context where it won’t work, I don’t know.</div>
<div><br>
</div>
<div>Possibly the Wow6432Node might be a better location to use to make it a bit more resilient.</div>
<div><br>
</div>
<div>Of course, if you want a system provided JAVA_HOME then that’s obviously the wrong approach to take!</div>
