IvAp Install in P3Dv4


How to install IvAp in Prepar3Dv4

You need the following files:

  • FSUIPC5.dll (Download FSUIPC5100.rar from our download area – folder FSUIPC)
  • SimConnect.msi {C67A3A1B-F52B-42CC-85E8-231428A09312} >>
    this file is in your P3Dv4 folder x:\P3D4\redist\Interface\FSX-SP2-XPACK\retail\lib\
  • the usual file from IVAO >> ivap-v2.0.2-b2773.exe

Assuming you created a specific disk or folder for P3Dv4… say disk:/P3Dv4/

  1. Install FSUIPC5 (non licensed works) and check the … \Modules folder
  2. Install SimConnect.msi (right mouse as administrator)
  3. Create a copy of the file Prepa3D.exe as in the root of your installation folder
  4. Rename this copy to fsx.exe
  5. Right mouse click the file ivap-v2.0.2-b2773.exe and install as normal as administrator in the root of your disk
    1. [so not inside … \P3Dv4\…not in ..\Program Files  (x86)]
    2. Exit the MTL process and/or the TeamSpeak process
  6. IvAp is activated by starting the sim through the file ivap_fsx_bootstrap.dll which is called by the dll.xml. This dll.xml is stored in this folder:
    C:\Users\yourname\AppData\Roaming\Lockheed Martin\Prepar3D v4\
  7.  Open the dll.xml with  Notepad++ and copy/paste to create this text:
    <Launch.Addon><Launch.Addon>
    <Name>IvAp</Name>
    <Disabled>False</Disabled>
    <Path>F:\IvAp v2\ivap_fsx_bootstrap.dll</Path>
    <Commandline></Commandline>
    </Launch.Addon>
  8. Check that the path of the bootstrap.dll file refers to your own disk/folder situation !
  9. Check the dll.xml to look like:
  10.  Adding the IVAO_MTL entry in simobjects.cfg
    1. Open the file  simobjects.cfg in C:\ProgramData\Lockheed Martin\Prepar3D v4\
    2. Add this text:
      [Entry.10]
      Title=IVAO MTL
      Path=SimObjects\IVAO_MTL
      Required=False
      Active=True
    3. Save the file
  11. Start the sim…you won’t see IvAp as usual in Addon
  12. Now press your Windows key and go to  the folder IVAO\
  13. Select the icon IvAp v2 – External | More and Run as administrator.

User Issues

Since the IvAp is still a 32 bits app, you might experience some strange events…

Weather: strange effects? Disable theh weather engine in the Configuration panel section Weather

Transponder: the transponder codes can only be set in standby position. In IvAp v2 – Configuration enable IvAp <-> FSUIPC SDK in the section 3rd Party Tools.
