Toon Boom Harmony won't open

Hi!
I just installed toon Boom Harmony but when I try opening it, it just instantly closes. Like I get to see the loading screen for a sec and then it closed instantly.
Why is this happening? Thanks.

This is just a user forum. Sometimes a TB employee checks in but you really need to contact Toon Boom Support so they can help you with your specific hardware.
