Hello Everybody,After downloading FG, I tried various times to start the program and always get a black screeen with the ERROR message:Rendertexture requires the following unsupported Open GL.....: WGL-ARD-extensions-stringinitialising....I would appreciate if anybody on this forum could indicate me what I did wrong, or how I can solve this problem.Thank you and regards,Berbo

What operating system are you using? What graphic card do you have? Which version of FlightGear are you trying to run?

Hello Hardraade,I am trying to install the FG version 9.9.My present operating sustem is Windows XP, the graphics card is S3 Graphics ProSavage DDRVery likely the Graphics card is not the best one to run FG. I was unable to find if my grahics card is OpenGL.Thank you for your insights.berbo.

Take a look at this Microsoft info site: http://support.microsoft.com/default.aspx?...kb;en-us;285912Your problem is most likely with your graphics driver. Cheers!
