After you have downloaded, installed and activated the Prepar3D® client we advise you to store the Zip(s) and Installation Folder in a save place. It’s a good idea to make an image from your license credentials and store it here also. When you installed according to the guidelines these are your created folders:
- C:Program Files (x86)Lockheed MartinPrepar3D (or the modified install location*)
- C:ProgramDataLockheed MartinPrepar3D
- C:Users*USERNAME*AppDataLocalLockheed MartinPrepar3D
- C:Users*USERNAME*AppDataRoamingLockheed MartinPrepar3D
- C:Users*USERNAME*DocumentsPrepar3D Files
DO NOT MOVE OR CHANGE THOSE FOLDERS!
* The only difference could be that you have installed P3D in an other location than advised.
