i think it is installed properly
today i tested with same results, actually when i tried loading default scenario with f22 then loading the FRC file, it brought up the pmdg 777 properly with everything as it was when i did the filight, but it kept pausing and going to beginning of the replay over and over, so i could not get a proper replay, are you tracking a problem like this/?
not sure how to get a replay to proceed properly
also i tried recording an airbus takeoff today, so i alt+tab and click record, then went back to p3d and then after a very short while of recording it displayed green message recording stopped
at this point it is just frustrating : )
