After latest update D5 won't even start

After updating the software I can’t even open D5, I click on the D5 icon but it does nothing.

Hello. Have you updated from the client side? Is it currently updated to 2.8? Which version were you using before updating?
I suggest you can try downloading the software from the D5 website and reinstalling it. D5 Render | Real-Time 3D Rendering Software
