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.

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 R1
779 = IS2018 R2
780 = IS2019
783 = IS2020 R1
784 = IS2020 R2/R3
787 = IS2022 R2

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

    I see schema version 771. So I guess this is IS 2011. – Omi Apr 17 '15 at 04:24
  • Yup, just added 2011/2012 values. Hope this helps! – BranLakes Apr 17 '15 at 04:30

If you cannot open a 770 ism, install installshield 2010 sp1, then try again.
