Find InstallShield version used for creating an ISM file

Question

I have an old ism file that I am trying to open. But I don't know what version of Installshield was used for creating the ISM project. Is there a way to tell this from the ISM file?

I'm seeing some issues when I upgrade the ISM file.

Answer 1

Open the ISM file with a text editor and look for "SchemaVersion".

755 = DevStudio 9 (Erstwhile name of InstallShield)
761 = IS11
763 = IS11.5 
765 = IS12 
766 = IS2008 
768 = IS2009 
769 = IS2010 
770 = IS2010
771 = IS2011
772 = IS2012
774 = IS2013
775 = IS2014
776 = IS2015
777 = IS2016
778 = IS2018
779 = IS2018 R2
780 = IS2019
783 = IS2020
784 = IS2020 R2

You may be able to use your version of IS if you change the value. See this discussion.
