Dear all,After a succesfull installation of PMDG737NGX 800-900 (3118 full installer) in my new PC, i proceeded with the 600-700 expansion (3118 full installer downloaded from PMDG). Attempting the 600-700 installation i faced the error "Feature transfer file - Catastrophic failure" and thus it is impossible to install and use my 600-700 copy.Is there anyone had ever the same issue? (I submitted a ticket in PMDG support but they said that is an OS issue and I' m wondering why on this specific installer only?)Any help will be higly appreciated,Regards,John
