Why is the installation of the cool sky dc9 so cumbersome.!..?
Just switched to W10 ,because w7 gave problems which I can understand.
Have installed the FSX file format and FSX old aircraft are working ok ,after conversion W10.
I can see during the purchased Coolsky DC 9 ,installation process ,that it tries to deviate from the FSX standard file and the software proposes to install the DC 9 else ware in W10 !,,
