Thanks for your reply everything worked perfectly , so it means when installing CS777 from the exe file it should be installed in The MFS 2020 community folder completely right ? because I installed it the first time in the MFS2020 folder but not in the community folder. after the installation in the Com.Folder ACE didnt require me to show where the path is because it read it automatically from the Com.Folder .

I just selected where I purchased MSFS2020, and it installed where it should have. It should have been the same for you.
