A customer was recently able to install this with 17.0.8 but it is still worth checking our latest installers and installers - 1

The issue persists with our 17.0.8 and 11.0.20 installers for Windows. We switched to the new installer scripts in the July PSU but that didn't bring the fix for some reason. Will investigate in time for JDK21/Oct-PSU.

The issue is also present in 21.x version installers.

Thanks @GeoSimos. Out of curiosity, why is this flag important to you?

Hi @brunoborges, I replied here https://github.com/microsoft/openjdk/discussions/295#discussioncomment-8628804.

@jmjaffe37 let's review if we need this feature at all.

If I recall correctly, this feature comes from the old days of JREs and integration with browsers.

If you can provide a way for us to detect the installed Java version and architecture, then it may not be required, however, lots of solutions are using those Registry keys to do several stuff.

Do you have some examples of tools that rely on this registry key to identify presence of Java installed?
