Setting the Product Code

InstallShield 2020 Express Edition

The product code is a string that uniquely identifies your product. An installation uses a product code at run time to determine whether the product has already been installed.

Enter a GUID that uniquely identifies your product, or click the Generate a new GUID button ({...}) in the Product Code setting in the General Information view to let InstallShield generate a new GUID. The installation registers this GUID at run time.

Caution:Because the product code uniquely identifies your product, changing the code after distributing a release of your product is not recommended.
