Launch error code

Hi, I’m on my pc on steam and I am trying to launch fc 25 on steam an error code pops up and says, This file does not have an app associated with it from preforming this action. Please install an app or, if one is already installed, create an association in the default apps setting page. 

If you could let me know if there is a way to fix this I will really appreciate it.

Thankyou
