I've read the FAQ's and searched the forums for tips on getting Real Weather to work, and in spite of everything I've tried, I still get the "Real Weather Not Detected" message.
Here's my procedure: link to the METAR download site from x-plane.com, then right click on metar.rwx, choose "save target as," and save it as a text file named "world.rwx" in the x-plane system main folder.
Checking and unchecking the Real Weather box has no effect. I have a clean install of 5.54 on a P4 with 256K RAM,running
WIN ME, with a 32 MB nVidia GeForce2 MX AGP card. 5.54 runs beautifully, except for no Real Weather.
Thanks for any advice. Maybe 5.6X will solve the problem, and it's on order.
