Have you changed default Windows 7 version by the way? According to Stream product page it should run on Windows 7.
The version of Wine I have defaults to Windows 7. The only way I was able to get it to run was to install the native windowscodecs via winetricks.
Otherwise it displays an error dialog "Error! - Couldn't find an effect variant to use for the primitive." with the missing CLSID message in the console.
