ThinApp User’s Guide : Configuring Package Parameters : Configuring MSI Files : MSIProductCode

MSIProductCode
The MSIProductCode parameter specifies a product code for the MSI database. Windows Installer uses the code to identify MSI packages.
The capture process generates a random and unique product code that is not taken from the application. The value must be a valid Globally Unique Identifier (GUID).
The parameter works only when the MSIFilename parameter requests the generation of a Windows Installer database.
Do not modify the MSIProductCode parameter.
Examples
The capture process can create an MSI file with 590810CE-65E6-3E0B-08EF-9CCF8AE20D0E as the product code.
