Issues during upgrading Prepar3D from v4 to v5
Did you find any issues with our plane while upgrading Prepar3D?
This happens because our product – as other planes – is installed inside P3D folder, so uninstalling the entire P3D causes the complete removal of this folder. In turn, reinstalling our product for P3D v5 will have problems because it will find the previous license already active. So, please uninstall our plane before the simulator, then install the new simulator and the plane.
If you uninstalled the simulator first, you won’t be able to uninstall our product, because it will search some libraries needed for deactive the license. To solve, you have to:
- recreate the P3D v4 main folder (it does not need to contain the P3D files, it’s enough that this directory exists). Typically is something like C:\Program Files\Lockheed Martin\Prepar3D v4\
- copy inside this folder the files that you can find inside this archive: https://drive.google.com/file/d/1bOEIM5V-zXhLHZZPY7_XU0pNuuqcX2vJ/view?usp=sharing
- ensure that the files have permissions. Sometimes Windows disable for default the execution of files coming from internet. If this is the case, right click on all files, and enable it:
- uninstall MB-339
- delete the folder created at step 1
- install again the MB-339 choosing on P3D v5
