Hello, I have two issues: I have AIFP3 and my FSX:SE is in D Drive (Windows 10) but AIFP3 gives a error that no flightsim is found

And I also have a issue with WOAI:

When I want to install the AI traffic into FSX:SE A error that a aircraft is not found (e.g. DJC_A319 not found) and also much more aircraft occurs. I had to reinstall FSX and Steam because it was placed in C Drive while it should be in D Drive.
