could somebody explain to me how to de-install P3D completely without any rememberance in registry?
I de-installed P3D and my Flightsimlabs A320 twice and after reinstalling P3D V5 still remembers
my loaded and saved aircraft configs of FSL. (?)

Now I have a weird Flightdeck view, and only in the view selection window I can get a small
window with my original 3 d flightdeck view. But I failed to get my original 3d flightdeck view back
on to the screen. my zoom views are screwed up as well. How can I get the 3 d cockpit view back on to my
full screen?

Everthing happened after installing ORBX LOWI airport scenery.

THX for your help!

Andy, you could also use the document I have pasted in below:

This is how I perform a clean install on Prepar3D v. 5, if you have v. 4 just say "v4" where the instructions say "v5".


WARNING: A clean install will mean just that - beware that all add-ons will not reappear in P3D, you will need to re-add or reinstall them, and that is beyond the scope of this tutorial.

I have my P3D v. 5 on my H: drive, a dedicated SSD. It is in a folder called P3D V5. For your installation substitute your own installation location, but - IMPORTANT - do NOT install to the default location of C:\Program Files. If you had P3D installed there, then install to somewhere else when you reinstall, for instance to C:\P3D.

The creation process begins with going to the Control Panel and uninstalling the old version: first uninstall the SDK, then Scenery, Content, Client and Professional Plus (or Academic) in that order.

Remove whatever remains under the folder P3D V5.

Go to Documents, remove the two Prepar3D v5 folders with Addons and Files from there. If you have moved your Documents folder, go to its new location and remove from there, of course.

Go to the root of C: drive, in the Search box in the top right-hand corner type "Prepar3D v5" (without the quotation marks) in Windows Explorer (that is File Explorer, not Internet Explorer). Delete everything that is found. Some items cannot be deleted, go Skip on those items.

Empty your Temp folders (not really necessary, but they should be emptied once in a while).

Empty your Recycle Bin.

Clean Registry, using Eusing's Free Registry Cleaner.


Right-click on P3D's Setup.exe and select Run as Administrator, and on the first screen, under Options, select to install in the P3D V5 folder on the H: drive. This is for my own use, see above for installing on another drive.

When the installation is finished. go into the P3D v5 folder, create a folder named SDK, install SDK to there.

Right-click on the Prepar3D icon on the desktop, select Properties. Go to the Compatibility tab, put a check mark in the box "Run this program as Administrator". Click Apply, then OK.

Start P3D, fly the default flight out of KRND (KVPS if v. 4) for a couple of minutes. Shut down P3D, reboot.

Go into the SDK subfolder, right-click on ConfigureSDK.exe and select Run as Administrator. Answer Yes to the question that comes up.

Now you are ready to explore the world of Prepar3D.

If you reinstalled P3D because you experienced problems with add-ons, then test the flights where you experienced problems BEFORE you install ANY add-ons.
