Hi, I was using OpenSCAD 2015 before and it was running good on my XP machine. Now I tried to install the 2019 version. Install went good, but when I start OpenSCAD now, I get an error message: Der Prozedureinsprungpunkt "Direct3DCreate9Ex" wurde in der DLL "d3d9.dll" nicht gefunden. (Could not find procedure entrypoint "Direct3DCreate9Ex" in DLL "d3d9.dll".) I searched for the "d3d9.dll" in my windows dir and found to files with the same version: C:\WINDOWS\system32\d3d9.dll Version: 5.03.2600.5512 (xpsp.080413-0845) C:\WINDOWS\ServicePackFiles\i386\d3d9.dll Version: 5.03.2600.5512 (xpsp.080413-0845) When I search a dll on the web, the version are pretty the same. Has anyone a clue, why I get this error message? ______ /hanks Martin -- Sent from: http://forum.openscad.org/
