Pre/Post build steps

[spintz]

I'm trying to do a simple copy command for a Post-build step and I keep getting this error -

Running target post-build steps
copy .\Debug\IrrSpintz.dll C:\WINDOWS\system32\
Execution of 'copy .\Debug\IrrSpintz.dll C:\WINDOWS\system32\' in 'C:\IrrSpintz\source' failed.

Any help please?

EDIT
Well, I guessed that because copy is a special "dos" command, you need to execute it from a cmd prompt, so I prepended - 'cmd /C ' to all of my commands and they worked.  It'd be nice to not have to do that.

Does the source file exist? Is the path to it correct? Do you (your running Code::Blocks process) have the permission to write to the target directory?

Edit: Well, solved without my comment.
