ReplaceFileW should fail with ERROR_ACCESS_DENIED when either the replaced or replacement file is set to read only using SetFileAttributes. Testing for the return values of ReplaceFileW was performed on a Windows XP SP3 and Windows 10 vm.
Remove GENERIC_WRITE flag when opening replaced file ReplaceFileW will fail when called to replace the current executable. This is not the same behaviour as tested on Windows 7, 10 and XP this is because the "replaced" file is opened with the GENERIC_WRITE flag. The MSDN also mentions that the replaced file is only opened with GENERIC_READ, DELETE and SYNCHRONIZE.
This patch will fix the following bug once it is merged into Wine-Staging as the WarFrame launcher requires patches from Wine-Staging to work. Wine-Bug:https://bugs.winehq.org/show_bug.cgi?id=33845
