So no backwards compatibility for the latest version of SODE and/or GSX?
There as been already a discussion on another thread about this, and we finally got to the bottom of this:
- The new installation system is supported since P3D 3.0, but it had quite a few bugs.
- The ability to add an addon by launching Prepar3d.exe from the command line to reconfigure the add-ons.cfg file, is supported only starting from 3.3. We found about this so, with 3.2 and before, we don't use the add-on.xml system with GSX, but it seems the SODE installer does, that's the reason of that error.
- Even if 3.3 had all the features supported by the installer, it WAS bugged, and *sceneries* added using the add-on.xml method still don't work and 3.4 is required.
Yes, it would be just so simpler if we just didn't allow any version lower than 3.4, it would make our life so much easier but, since some users seem to want to keep the bugged 3.3 for reasons I still don't fully understand, we updated ALL our installers again now, and are using the new installation system only in 3.4 and 4.0
However, if you want to stop the error while installing SODE, you must either upgrade with 3.4, or wait if a new SODE installer will eventually be able to deal with all those differences.
Back then, with FSX, life was much easier: you either installed the SP2, or nothing would work. Everybody installed it, nobody complained...
