SetErrorMsg Example

InstallShield 2019 » InstallScript Language Reference

Note • To call this function in a Basic MSI setup, you must first create a custom action for the entry-point function, execute the custom action in a sequence or as the result of a dialog's control event, and then build the release.

* InstallShield Example Script

* This script customizes the error messages displayed after a

* call to EnterDisk if the next disk in a set of setup disks

* is not ready in the specified drive.

// Define the text messages for EnterDisk errors.
