P3D installation disk

Postby wenildexis5 » Wed Sep 09, 2020 12:39 pm


Being P3D V3 and XP11 user, I wanted to upgrade from P3D V3 to V4, all is good till I try to install the V4, because it is trying to install in the wrong hard drive, in the installer I select that I want to install it in a folder on my D: drive where I have 200GB free, but instead it is trying to install in C: drive where there is 10GB available, so that causes the installer to stop due to too little space. I checked my P3D V3 installation, while its folder is in my D: drive, but under programs page it is showing that it is in C: drive. All in all a weird situation. Anybody knows how to fix this?

I am pasting in here a document I wrote primarily for a clean install of v. 5, but there are notes in it for v. 4.

With this you should be able to make a complete uninstall of v. 4. After that, check v. 3 for functionality before you attempt to install v. 4 - this shows you how to install onto a different drive than the C: drive.

Read the whole thing first, maybe print it out.

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).

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.
