HALion 7 update question

Can you still use HALion 6 whilst you are getting the hang of 7 when you update?

No ,Halion 6 gets updated to Halion 7 , unless you install Halion 6 and the Elicencer on another computer

HALion 7 replaces HALion 6, but if you know your way around 6, then 7 won’t be a problem.
