if you want to delete a file in vista/win7 system dir like c:\windows\winsxs\xxx.dat,
you must change the file's owner to administrator and add an allow ace with it.but i want to create or
delete file in system dir in my program by calling api like CreateFile or DeleteFile, but its return value
is 5, can not access. how can i do?

You might have admin rights but that does not mean that whatever process you are using to create/delete files has admin rights.

Solution 1

Error code 5 means ERROR_ACCESS_DENIED as described here[^]. You need to add a manifest to your project that requests administrator privilege for the program, or use the "Run as administrator" link in Windows Explorer when starting it.
