Error Message: "The installed version of the application could not be determined. The setup will now terminate."

Error Message: "The installed version of the application could not be determined. The setup will now terminate."

Summary

When running an Installscript installation, the message "The installed version of the application could not be determined. The setup will now terminate." appears.

Symptoms

When running an Installscript installation or upgrade, the message "The installed version of the application could not be determined. The setup will now terminate." appears.

Cause

  1. If the message shows up during an upgrade, the variable IFX_INSTALLED_VERSION and IFX_INSTALLED_DISPLAY_VERSION is not being populated in OnSetUpdateMode. This is due to previous version of the install being built by a very old version of InstallShield.
  2. If the message shows up during a first time install, the setup requires administrative permission.

Resolution

  1. Populated the variables IFX_INSTALLED_VERSION and IFX_INSTALLED_DISPLAY_VERSION in OnSetUpdateMode. The explanation and code to resolve the issue are commented out and are already available in OnSetUpdateMode.
  2. Run install as an administrator.
