Title
ISM project file opens earlier version of Installshield

Summary

If there are multiple versions of Installshield on a single machine double clicking an .ism project may force the earlier version of Installshield to open rather than the latest.

Symptoms



If there are multiple versions of Installshield on a single machine double clicking an .ism project may force the earlier version of Installshield to open rather than the latest.

As an example if a machine contains Installshield 2012 Spring, Installshield 2013 and Installshield 2014. Double clicking an .ism created in 2014 may result in 2012 Spring to launch displaying an error that the project can not be opened.

Cause



This can happen if Windows primary focus is not on the latest version of Installshield.

Resolution



Performing a repair on the version of Installshield you wish to have primary focus will cause that version to open when double clicking .ism project files.

This can be done by locating the version of Installshield you require in Add/Remove Programs in the Control Panel and selecting repair.
