Hi Eduardo

Based on my understanding, you want to modify the configurations of a msi
package at run-time(while it is being executed), please let me know if I
have misunderstood anything.

AFAIK, most properties of a MSI package cannot not be modified at run-time,
the package just likes an ordinary EXE while running. But you can modify
the package via the VBScript before run-time, just as you use the MSI
utility ORCA.EXE to edit that package:

The sample VBScript files will show you how the Windows Installer
automation interface is used to modify Windows Installer packages, please
refer to the following MSDN SDK documentation link:

indows_installer_scripting_examples.asp

Thanks!

Best regards,
