Hi, On my Vista Ultimate 32 bit I am not able to start Windows Meeting Spaces. I walked through the steps described in Windows Help (Checking services, IPv6 enabled, ...). But this didn't help. During my investigations I noticed that this seems to be a user specific problem. Using another User it's working. In Control Panel People near me is also not able to start (Element not found). Other users on my computer are able to start it. Thanks for support! Franz
