In the install screen there are options for FSX Box, FSX:SE standalone, FSX:SE side-by-side with Box, and P3D. I have both FSX Box and FSX:SE installed. Do I need to install with the FSX Box option first, then install again with the side-by-side option? Or can I just forego the Box-only install?
I, like DVA238, also hate to revive old threads, but the FRDMM3 arrival into DCA causes this error as well. KSTL - KDCA via JHART3 CREEP J80 AIR J34 BUCKO FRDMM3 With just the arrival inputted (runway 01 transition), the error appears instantly.
