Please Note: If you originally Installed Prepar3D v4 by running the component Installers Individually you will not have a  Prepar3D v4 Academic \ Professional in your Control Panel 
 
You can just Right Click on each of the components Client, Content and Scenery and Click Uninstall

 

-----------------------------------------

 

2)  Deleting the 6 Prepar3D v4 folders 

While the uninstaller removes all files that are created by the installer, it does not completely remove content that was generated during program execution. To completely uninstall Prepar3D, you must manually delete folders and files that are created during runtime.  

Note: To locate these folders, Insure the box is Ticked for  Show hidden files, folders and drives in File Explorer Options

 

For a clean Uninstall, please manually delete the following 6 blue folders:

------------

Local Disk (C:) ► Program Files ► Lockheed Martin ► Prepar3D v4  (or the modified install location)

Documents ► Prepar3D v4 files \ Prepar3D v4 Add-ons

Local Disk (C:) ► ProgramData ► Lockheed Martin ► Prepar3D v4 

Local Disk (C:) ► Users ► You ► AppData ► Roaming ► Lockheed Martin ► Prepar3D v4

Local Disk (C:) ► Users ► You ► AppData ► Local ► Lockheed Martin ► Prepar3D v4

------------

 

Restart your computer.    You have now successfully Uninstalled and Deactivated Prepar3D v4 from your computer 

You are now ready to Reinstall again
