Good morning David. Ever since vtk\_9.4.1 was released, I have been building the **RELEASE** version with vs 2022. The build was clean but java would not load, never mind run. The loading error suggested missing DLL’s of which I downloaded many in trial and error. Nothing worked and I almost gave up.

I have just built the **DEBUG** version of it and it **LOADS & RUNS**! There is obviously something in DEBUG that is missing from RELEASE. No idea what it is but I shall look for it while happily running my new vtk\_9.4.1 on Java 8.  
Thanks to the team for all the help.
