The declaration for Exec is:

procedure Exec(Path, CmdLine: string);

So the compiler is treating myutil.exe as a variable name / identifier, 
but since it hasn't been declared as one the compiler throws an error. 
You probably need something like:

Exec(GetEnv('COMSPEC'), '/C myutil.exe);

GetEnv('COMSPEC') will return the full path to the command interpreter, 
and the '/C myutil.exe' will complete the command line you need.

Hope this helps!

Dave
