I get this as well, it delays the game launching for about a minute to a minute and a half and then i'll get the message "Connection to the Larian support server failed. The Larian support tool will be disabled. The operation has timed out - " after I acknowledge the dialogue boss it'll disappear and then 5-10 seconds later i get a notice that there's no disk inserted in drive e. hitting continue or cancel it'll then launch the game proper.

I had read in another thread that launching EOCapp.exe as an administrator would bypass this and it does but by launching that file the game doesn't connect to steam for online play. please find a way to fix this devs.
