MSIUpgradeCode–
Specify an upgrade code for the MSI database
This option has an effect only when generation of a Windows
Installer database is requested via the MSIFilename option.
It is highly recommended that each MSI database has an UpgradeCode.
SetupCapture will generate a suitable default UpgradeCode and place
it in Package.ini. There should be no need to change it. If you do
change it, make sure the new value is a valid GUID (Globally Unique
IDentifier).
For more information, see MSI
Generation.
This creates a .msi file with a specified upgrade code
