Simlink won't connect to P3Dv5 but does connect to v4

After reviewing every forum post I could find about Simlink not connecting to sim here is my details. I have P3Dv4 on my C: drive and v5 installed on my X: drive. V4 will connect to simlink but v5 will not. I checked p3dv5 add-ons folder per the post about multiple versions and there is no shortcut showing for v5. I checked my simlink Plugin Settings and both have the green check mark and they look like the path in the Simlink install and Systray post dated Sep ‘20 –
C:\Users\ \Documents\Prepar3D v5 Add-ons\Navigraph Simlink (for v5; the same for v4 except for being in the v4 Add-ons). I have redone an uninstall and reinstall of simlink several times and it says it is successful but the results are the same.

The other thing I noticed is there is no listing inside my v5 sim Addons menu for simlink but I don’t know why it is not connecting after searching this forum for a fix.

Here is the Navigraph Simlink xml text in my v5 add-ons folder:

<?xml version="1.0" encoding="utf-8"?>

<SimBase.Document Type=“AddOnXml” version=“5,0” id=“add-on”>
<AddOn.Name>Navigraph Simlink</AddOn.Name>
<AddOn.Description>Sends simulator reports to Navigraph Charts</AddOn.Description>

The path to my v5 install is: X:\Lockheed Martin\Prepar3D v5
My simlink version is and is set for Auto updates in the settings.

Any help would be appreciated so I can get this working.

Hi Jerry,


Do you have NavigraphSimlink_64.dll in c:\Users\username\Documents\Prepar3D v5 Add-ons\Navigraph Simlink ?

If not maybe copy it there from c:\Users\username\Documents\Prepar3D v4 Add-ons\Navigraph Simlink


Ian, I did have the 64.dll file in v5 Add-ons\Navigraph folder. Just in case of corruption I copied the file from v4 Add-ons\Navigraph folder but still the same - won’t connect to v5.

Hi Jerry,

In P3Dv5 \Options\Add-ons make sure Navigraph Simlink is enabled.


That was it Ian, for some reason the box was unchecked. Now I can connect to v5 on the moving map. Is there supposed to be some mention of Navigraph or moving map in the p3d Add-ons pull-down menu? There is no mention of it there but the pink arrow is connect on the map.

Thanks for your help, I appreciate it.

Hi Jerry,

There is no notification other than Navigraph Simlink. I don’t know why this occasionally gets unselected. :thinking:

You are welcome. Glad it is resolved.

Happy flying
