Intersting observation.It appears I can run Hitfilm Pro 4 and Hitfilm Pro build 7.1.0002 at the same time on my Mac. Not wanted behavior? (Not complaining)
Let me tag @CedricBonnier.
I know with earlier versions the way proxies worked would prevent multiple instances of Hitfilm from running (with Hitfilm 1 or two as exceptions - no proxies). I don't know if this changed in v6+ or you found a bug. Since the installed file structure changed with v6, it's possible you might be able to run v8 concurrently with v4, but I know you can't run two instances of v8.
I actually keep Ultimate 2 installed so I can start a new project while a later version renders.
Hmm, I'm wondering about the same thing as well.
