i use the fsuipc logo to start fs2020, the fuipc splash sreen logo comes on for one second and disappears. from then til the sim starts where i can choose aircraft and airport is very long , about ten minutes.
not sure of any sim updates as such, navdata update done before this all started,
fsuipc versions 751, 752e,752. all produced the same errors in connection but all versions each would work a least once but then not work after that,\9now im confusing myself).
no matter what version i use, if fs2020 is started and fsuipc is running, when i connect cpflight and i see autoconnect icon on the init screen then i know its working right, if that autoconnect and check box isnt there its not gonna work right. im gonna try a flight now and report back.
