When i try to install FAF client it creates only few files in direct folder. Not all - so i can't play. After ending of install dfc_windows-x64_1_5_0.exe this exe file autodeletes. I turned off all antiviruses. Didn't helped.
UPD: Solved with anti-virus turning off
This is almost certainly some other anti-virus or permissions on your system not allowing the client to be installed.
Solved, read UPDATE of topic. If topic can be closed - pls, admins, close it.
