Is it safe to delete FLEXnet Publisher from my Mac

I think the title of my thread says it all.

There is something called "FLEXnet Publisher" on my MacBook Pro and I want to delete it. I don't like things on my Mac with which I am unfamiliar and especially things I did not install.

I understand it is some kind of licensing thing, but I still want it gone. Maybe it's the reason my totally-paid-for Photoshop software isn't working properly, and after owning it since the early 2000s suddenly thinks I don't have a license for it. I not only have a license for this copy of Photoshop, I purchased THREE licenses at the same time for three separate copies of Creative Suite. Frustrating!

Still, I want to be safe. Anyone?

Running OS 10.13.3.
