David,
There is some think wrong with my 767ACE. I installed TWA from TWA 767-3Y0, Circa 1996  .Then also tried from AVSIM.
All installed into ....Flight Simulator X\Captain_Sim\767\variants folder. When I opened  ACE/ADD NEW/Select Variation\TWA zIP file doesn't appears in C:\...Captain Sim SECTION.
I also uninstall/install 767. Still ACE does not receive TWA Zip file.
What am I doing wrong?
Thanks :-[
