In the process of installing TWOS, it appears that "sh5.exe" is being used by another process, and then it is wrong.
My sh5 is the steam version, and then in accordance with the TWOS installation tutorial to the "Silent Hunter 5" the read-only property of the folder, but find a problem, after the read-only property is canceled, then open to read, read-only has been automatically selected by the system, how can this error be eliminated? When I install TWOS, I also shut down uplay and steam.
My computer system is windows7, My computer system is already an administrator...and I haven't worked for half a day.

Can you ask you for a moment? Be deeply grateful!
