Unable to start game - Steam error (Solved)

Hello,

I could start the game fine yesterday but today I receive a steam bx on the screen with the following information.

Steam error
Failed to start process for boundless
“Access denied” (0x5)

with a link to support pages which doesn’t help.

Boundless updated earlier so maybe the problem. I have validated files, restarted steam and PC but still the same message. I am able to open other games no problem.

Thanks for your help.

Do you have any antivirus notifications displayed on screen as this was happening? A few players have posted here with issues regarding AVG and Avast:

You Sir are a genius, it looks like Avast started blocking it following the update, normally I would have calmly worked through different options till solved but went into a panic! I may have an addiction :frowning_face:

Many thanks.
