My P3D V4 doesn't not want to load with UT2 server because it fails to load due to ' {smartassembly} is not available on this computer' error after I did a clean install of window. It had been working fine before and I already did the followings according to my online search on the problem:

1. installing the old simconnect provided in FlightOne forum

2. Install legacy all the simconnect in Prepar3D v4/redist/Interface/

The two methods above don't work for me. I am running out of idea so decide to seek help here. Am I missing others programs that I should install...maybe?

 

 

Make sure that you have the required Microsoft.Net files installed

I think windows 10 already comes with .Net 3.5 which is required by UT2 according to https://www.flight1.com/products.asp?product=ut2

I am trying to remove .Net comes with windows and use the installer I downloaded from the internet.

This fixes it! Unload the default .Net 3.5 that comes with windows 10, and install the one found in Microsoft website.
