I had InDesign CS3 (old version), and recently purchased InDesign CC and got it installed in my system. But as I prefer working with InDesign CS3, I kept that old version too and but after around 2-3 months, InDesign CS3 stopped opening, earlier after restarting system, it used to start but it didn't open. So I had to remove InDesign CC to keep working in InDesign CS3. My organisations' technical team is saying its clashing with older InDesign CS3.
Please advise, how to keep using InDesign CS3 & InDesign CC in the same system.
