Thanks for the insight. We’ll need to ensure that the check runs with all versions of Windows that we support, but if a similar problem is reported back to us again, we’ll think about a multi-step version check.

Mr. Grun,

It seems that the Windows Management Instrumentation Command-line (WMIC) command line utility gives a reliable result in windows.

It is deprecated, but working on any Windows OS, including Windows Server 2022.

On my home machine with Windows 10 OS the following command c:>wmic product where "Name like '%JRE%' or name Like'%Java%' or name Like'%JDK%' " get name,Vendor,Version

emits the following 4 (four) Java installations:

Name Vendor Version Java(TM) SE Development Kit 18.0.2 (64-bit) Oracle Corporation 18.0.2.0 Java 8 Update 391 (64-bit) Oracle Corporation 8.0.3910.13 Eclipse Temurin JDK with Hotspot 21.0.2+13 (x64) Eclipse Adoptium 21.0.2.13 Java Auto Updater Oracle Corporation 2.8.391.13

To see all available entries: c:>wmic product where "Name like '%JRE%' or name Like'%Java%' or name Like'%JDK%' " get * /format:textvaluelist

So, you can try to integrate wmic based method in the BaseX Windows installer.
