Use elevated privileges to get UAC to allow you to write into that directory.

Add a manifest to your project, which requests Administrator privilege, or use "Run as Administrator" to run the program.

See http://msdn.microsoft.com/en-gb/library/windows/desktop/aa363851(v=vs.85).aspx for other reasons that this may fail.

Solution 1

"to copy current program" - no, that cannot work. Your program is running, that means the executable file is being executed, it is in use. Elevation won't help you here.

it means it have no way to copy this program ??

Interesting: I assumed that CopyFile would still be able to read it, even though the program is running.

No. An executable file can be copied while it is being executed. You're wrong. I tested it by creating a console application which copies itself while it is being executed. OP may have any other problem.
