This is extremely frustrating - I'm using Parallels Desktop 8 from behind a corporate proxy. Lots of other applications are using the system-wide proxy settings just fine, and yet it seems that PD8 refuses to do so. Whenever I: 1. Check for updates 2. Attempt activation 3. Try to register the product Parallels Desktop will just sit there for a while and come back with some cryptic error message, sometimes with a link to a "solution" that just takes me to the generic knowledgebase web page. I'm almost certain it's proxy settings, because when I take my laptop home, where there is no corporate proxy in effect, I can do all of these things without any problems.
