[Bug 45611] 64bit prefix: copy file to system32 incorrectly copied to syswow64

https://bugs.winehq.org/show_bug.cgi?id=45611

--- Comment #4 from [e-mail] ---
I tested copy behavior on windows 7 x64:
32bit `copy 00aa.txt c:\windows\system32`  copy file to syswow64
64bit `copy 00aa.txt c:\windows\system32`  copy file fo system32
Launch cmd via start menu's run box will launch the 64bit one.

This isue was found when i was making a bash script to manually extract
dotnet40 for 64bit prefix using wine's copy: no file copied to system32 dir,
same result as winetricks. I use meld compared changed dirs.

Was that `dotNetFx40_Full_x86_x64.exe` running on a wrong environment or it was
calling the wrong cmd? This was my think.
