Navigation data halts XP 12

Navigation Data General non MSFS data

Thanks Dudley, and you can confirm that you don´t have a second X-Plane 12 copy somewhere, right?

When you compare the X-Plane 11 folder with the X-Plane 12 folder you see, that there are a lot of additional files, which are not correct.

Close the sim!

Please delete following file/folder from the X-Plane 12 directory:

  • 1200 atc data complete folder
  • CIFP complete folder
  • Custom Data folder
  • 17271467...index file
  • cycle.json file
  • cycle_info.txt file
  • all earth_*.dat files

When all is “clean”, run the XP12 installer again to update all files (the Custom Data folder will be restored with the default dataset).

When this is done, close the installer and start the X-Plane.exe file DIRECTLY!!! from E:\StreamLibrary2\steamapps\Common\X-Plane 12. It´s VERY important, that you do exactly this step.

When X-Plane 12 is loaded, without any error messages, close it again.

Open the FMS Data Manager → goto Addon Mappings and press the scan button.

Report back what happened than please.

Thank you,
Richard

PS: please, please, please do all these steps in exactly this order - this is really important to get a clean installation - currently you don´t have it
