Setting the Product Code in a Windows Installer–Based Project
InstallShield 2020
Project:This information applies to the following project types:
| • | Basic MSI |
| • | InstallScript MSI |
| • | MSI Database |
| • | Transform |
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.
