Insalations Problem

Recommended Posts


When installing I always get the error message."Problem! Cannot edit the Prepar3D v4 DLL.XML file to activate FSUIPC.Please make sure you run Prepar3D v4 at least once before installing FSUIPC!".I use p3d v4.5.12.30293 with GSX, PMDG (777,747,737), FSCaptain 1.8.1 and Active Sky for P3Dv4.

Here is the text from the installer

Does anyone know what I'm doing wrong.

That looks fine. I'm not sure why FSUIPC cannot find it - was it in the location I gave?

Presuming you have actually ran your current P3D version at least one, could you first try running the installer again.

If it fails again, you can try manually adding the following xml to the bottom (before '</SimBase.Document>') of you dll.xml file:

  <Name>FSUIPC 5</Name>
  <Path>E:\Program Files\Lockheed Martin\Prepar3D v4\Modules\FSUIPC5.DLL</Path>
