Microsoft decided that the API used for functionality of the TMacroRecorder component is a security risk on Windows Vista. Therefore, Microsoft disabled the API used for recording & playing mouse & keyboard events back in Windows Vista by default. In order to have this functionality enabled for your applications it is required:

• Digitally sign your executable. See http://stackoverflow.com/questions/252226/signing-a-windows-exe-file
• Run your executable as adminstrator or elevate rights to administrator
• Deploy your application under \program folders

With this applied, TMacroRecorder works fine on Windows Vista/Windows 7 or newer.
