Thanks Dave, that was what I was afraid of. Now I suppose I will have to experiment with one of the newer builds and see if I can find the magic incantation, or a zip file with all the necessary extraneous dlls that seem to be necessary with the newer builds. I suppose that is what retirement is for, though it would help if the maintainers put together a compliation of the actual dlls they use (not a list of rpms which may or may not work) to run their build.
In passing I must thank you for your 17.0.11 esr build that has worked so well for so long.
