Run an external program at the beginning of the
installation.
Your options include:
- Specifying an .exe, .com, .bat, .pif, or .dll file to
execute.
- Entering command-line parameters for the executable files.
- Entering the function that is run from a .dll library, as well
as an input variable that is necessary to run the .dll. The
$DLLRETURN$ variable uses an integer, unless you add str after the
variable. For example, 128, str is an acceptable variable
name.
- Specifying whether the .dll returns a value. The default return
type is an integer. If your .dll returns a string, check the
Function Returns a String option. The string is saved in the
$DLLReturnStr$ variable.
