The following patch does correct the behaviours I was trying to fix and now the tests I modified/added work as expected it also removes the low level checks that Dmitry wasn't happy about in the v5 attempt but seems inellegant so I'm hoping for some feedback on what I should really do.
--------BEGIN ACTUAL PATCH-------------------------------------------
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.
Open replaced file without GENERIC_WRITE flag if a sharing violation is returned on the first call checking for the READ_ONLY attribute. ReplaceFileW should not fail when called to replace the current executable which is the case 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
