Hi,

I have an issue with Ivap, I installed it, the same for the MTL, went in the dll.xml to add  

<Launch.Addon>
     <Name>IvAp</Name>
     <Disabled>False</Disabled>
     <Path>C:/Program Files (x86)/IVAO/IvAp v2/ivap_fsx_bootstrap.dll</Path>
     <Commandline></Commandline>
   </Launch.Addon>

 

But even after that, I don't see Ivap on my selection addon menu

 

I remember having the same issue once with P3D V3 but I didn't remember how I fixed it 

 

Regards

I believe you have this problem with V4.  This may help: Link

Briefly, you have to run "IvAp v2 – External", in case of Prepar3d V4.
