That was it, I should have remembered the wx file issue. Thanks a lot Pete, very much appreciated.

Thanks for responding. Installation was ok with all versions. Log file attached. I disabled all other modules in the dll.xml and tried with fsuipc only but a few second after start Prepar3D either quits without any notice or hangs and then crashes. I tried 5.122 and all versions of 5.123. I also tried with stock aircraft, other add-on aircraft and both stock and add-on airports. With and without reshade. I can't say that this is caused by FSUIPC, however without it in the modules folder these crashes don't happen. FSUIPC5.log

Unfortunately not for me. Including 5.22 I had no luck to get FSUIPC running in Prepar3d 4.2.
