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.
