Game launch error: failed to start (error code 51)

[samm]

Description:

Much like it was the case for Southpark (Link to relevant topic), Steam won't launch the PoE public beta. It throws an error code 51 instead.

 

Expected behaviour:

Game launches.

 

Reproduce:

1. Install FSecure Antivirus and update it.

2. Try to launch Pillars of Eternity beta from Steam

 

Workaround:

Go to Antivirus settings and set "compatibility mode" for Deep Guard, or disable Deep Guard.

 

Fix:
Obsidian should contact FSecure and register their game as non-virus or something like that...

Same issue for me with F-Secure Internet Security TP 2.15 build 358. I'll forward this to F-Secure.
