64 Bit Exe Loading - "Unable to locate a running instance of Steam"
New, NormalPublic

Description

I noted that if you went to the folder where DayZ is located in your Steam directory and attempted to run the 64 bit edition of DayZ either by double clicking on the exe or right clicking and using the run with graphics processor command it gives you a "Unable to locate a running instance of steam" error window. This occurs even though Steam is running.

The game attempts to boot the 64 bit version however boots the 32 bit version instead.

  4. In task manager window you will see the 64bit version loaded however no CPU resources are being used.

Additional Information

Please see attached screen shot of error message and task manager. Note that the MSI graphs were for an edit of another issue. You can see the Steam window in the background of the image.

Pushing the play button and selecting the 64 bit or right clicking on the game in the library window of steam and selecting the 64 bit version boots the game properly.

Thanks Ghost. That particular way to boot the game works properly.

Yeah it must have its own set of special parameters/flags when it launches the exe.
