In the FSX time I had IvAp installed so I could fly online. Since I installed Prepar3D I had not flown online because I had been busy with my simpit. This is almost finished (for now) so online flying is back in view, but the installation went far from automatic (on the contrary).
After the installation, according to the installation program, there was no IvAp entry within Prepar3D. The Prepar3D installation of IvAp has gone wrong. After some investigations there were some files that had not been adapted by IvAp. Below are the steps to manually install those adaptions so IvAp will work within Prepar3D.
- First make sure there is a fsx.exe file within the Prepar3D directory. This can be accomplished by renaming an empty text file or copying Prepar3D.exe and renaming that.
- Install IvAp with the installer and make a choice between a single or multi computer setup according to your own setup.
- Choose a FSX installation and navigate to the Prepar3D directory.
- You will get an error about the registry but you can ignore that.
- If you allready have an installation of MTL, you don’t have to install that again, else you will.
- Then decide how Prepar3D is run, windowed or full screen. I advice you to choose windowed. If IvAp crashes (and it will) Prepar3D will still run.
- Do not install FSUIPC, you will probably have a more recent version.
- Choose where you want IvAp to be installed and remeber this location.
- Install TeamSpeak.
- Make sure you have the latest (Prepar3D compatible version) installed.
To make a connection with Prepar3D you will need SimConnect. Do not use the Prepar3D version but the FSX version.
- This has been installed during the Prepar3D installation and can be found in the “redist / Interface” directory.
- You will find a number of directories. First install from the “FSX-SP1 / retail / lib” directory and afterwards from the “FSX-SP2-XPACK / retail / lib” directory. Both by starting the “SimConnect.msi”.
After installing IvAp it resides on your hard drive, but there is no link to it from within Prepar3D. This has to be done manually by following these steps.
- Go to the AppData directory. Hold the Windows key while pressing the R, then type %AppData% and press Enter.
- Go to the “Lockheed Martin / Prepar3D v2” directory. There you will find the “dll.xml” file. Open it with your favorite text editor and add the following lines directly after the lines with comparable content:
<Path>C:\Program Files (x86)\IVAO\IvAp v2\ivap_fsx_bootstrap.dll</Path>
Make sure that the “Path” is the same as where you installed the software.
- Save the file and check if the IvAp entry is visible within the Add-on menu of Prepar3D.
The MTL files are installed, but there is still no link to them from within Prepar3D. You will also have to do this manually.
- Again go to the “AppData / Lockheed Martin / Prepar3D v2” directory as described above.
- Open the “Prepar3D.cfg” file with your favorite text editor.
- In the “[Main]” section you will see a number of lines with “SimObjectPaths”. You will have to add the next line:
- Make sure that the number (in the line above “7”) is 1 higher that the highest present number.
- Save the file again and start Prepar3D once again to see if everything is working correctly.
- It is possible that you will have to reboot your system to get all changes working.
