I'm running into a problem with the latest version of Steam and current wine builds. For some reason when the windows version is set to Windows 7 under winecfg, Steam will require admin privileges for the installation of a service component. But even after going through the installation, it is obviously not detected:

err:eventlog:ReportEventW L"Failed to load Steam Service library."

The problem can be seen with Portal 2, and what's worse, I think it also popped up with the new XCOM demo.

Has anyone been able to successfully install the component?
