That thread was advice in the file Poser.ini from LIBRARY_IS_AIR 0 to LIBRARY_IS_AIR 1 , to make it use Adobe Air. But always something changed it back to LIBRARY_IS_AIR 0 , and my Poser 10 exited on startup as usual. I suspect that someone in charge of Poser 10 did not trust the result of Poser 10 running with Adobe AIR, so he put in a bit of program to look what LIBRARY_IS_AIR is set to in Poser.ini and change it to LIBRARY_IS_AIR 0 .
