I tried to install the Addon Manager. But when I start the sim and it put an error "Addon Manager will not run. FSX with SP1 or Acceleration or SP2 is required!".
That's either your registry keys for Prepar3D or FSX are wrong, pointing to the wrong folders OR you (or some migration tool) has meddled with the executable, like running Prepar3D with a renamed executable.
One friend, he´s programmer, saids me it is an error with the bglmanx.dll. I tryed to use other bglmanx.dll (Reinstalling Addon Manger) but it doesn´t work.
Your friend is wrong, and he can't possibly know how the Addon Manager works, and it works correctly, provided Prepar3D and FSX are installed correctly.
Which means:
- Prepar3D registry keys pointing to the Prepar3D folder. FSX registry keys pointing to the FSX folder.
- Prepar3D launched with the real Prepar3D.EXE, NOT by a renamed FSX.EXE.
Which means, don't touch anything from the default installations for both sims. You should see a question if you want to install in Prepar3D, which you should obviously reply YES to it.
If you have BOTH FSX and Prepar3D installed, and you don't see the question to install into Prepar3D, then IT'S SURE your registry keys for Prepar3D are messed up.
