[Bug 41934] Spreaker Studio 1.4.2 fails to install

https://bugs.winehq.org/show_bug.cgi?id=41934

--- Comment #6 from Sagawa  ---
The patch looks good to me.

I found out source code of the installer [1]. It seems that the installer
doesn't support Windows 7 in per-machine install mode then. So, it's reasonable
to add "AC" to known SID string to work correctly.

BTW, I misunderstood Security Descriptor (in
ConvertStringSecurityDescriptorToSecurityDescriptorW) and Security Attributes
(in CreateDirectoryW) in the previous comment. So, original code makes sense at
that point.
