try using WinExec, but this function is provided for compatibility with earlier versions of Windows.
WinExec(pchar('c:\Happyface.exe'),sw_ShowNormal)

Maybe you can use FileExecute() :
Example : FileExecute('NotePad',strFileName,strFilePath,esNormal);

Oops,
forgot to mention that this is a function which comes with the RxLib, and that you have to declare RxShell in the Uses-Clause.

Maybe after all, this is not what you are looking for.
