Installing More than One Edition of InstallShield

Only one edition of InstallShield 2025—Premier, Professional, or Express—can be installed on a system at a time. In addition, the InstallShield 2025 DIM Editor cannot be installed on the same machine with any edition of InstallShield 2025.

Microsoft Visual Studio can be integrated with only one version of InstallShield at a time. The last version of InstallShield that is installed or repaired on a system is the one that is used for Visual Studio integration.
