Click the Generate GUID button below to use a new GUID for your package code. Please note the difference between the package code and the product code. The package code is the GUID (Globally Unique Identifier) for your setup package. The product code is the GUID for the application that you are installing.

By default, this value is overridden when you create a new release because the Generate Package Code property is set to Yes in the Releases view. Because Windows Installer requires any two MSI databases with identical package codes to have identical contents, you should change the package code before releasing a modified package.
