Upgrading Projects from InstallShield 2013 or Earlier
InstallShield 2020
The following information describes possible upgrade issues that may occur when you upgrade projects that were created with InstallShield 2013 and earlier to InstallShield 2020. It also alerts you to possible changes in behavior that you may notice between new InstallShield 2020 projects and projects that are upgraded from InstallShield 2013 or earlier to InstallShield 2020.
General Information about Upgrading Projects that Were Created in Earlier Versions of InstallShield
If you use InstallShield 2020 to open an project that was created with an earlier version, InstallShield 2020 displays a message box that asks you if you want to convert the project to the new version. If you reply that you do want to convert it, InstallShield creates a backup copy of the project with a file extension such as .774 (for an .ism project) or .2013 (for an .issuite project) before converting it. Delete the .774 or .2013 part from the original project’s file name if you want to reopen the project in the earlier version of InstallShield. Note that you cannot open InstallShield 2020 projects in earlier versions of InstallShield.
You can upgrade projects that were created with the following versions of InstallShield to InstallShield 2020: InstallShield 2013 and earlier, InstallShield DevStudio, InstallShield Professional 7 and earlier, and InstallShield Developer 8 and earlier. Note that projects that were created with InstallShield MultiPlatform or InstallShield Universal cannot be upgraded to InstallShield 2020.
