Installing Microsoft Silverlight without administrative privileges?

no, why are you trying to install silverlight on a protected network computer (infact why would you want to install silverlight on anything?)

This kind of commentary is useless and leads nowhere.

First of all why installing Silverlight or Flash on a protected network should necessarily be bad? Most network administrators are security freaks! Security is important but before forbidding any access in the name of "security" administrators should be analyzing what is really a potential risk for the network and what is not. Flash or Silverlight are technologies that have been conceived with a high security concern (sand box, security messages, user warnings etc.) In my opinion, those technologies are the web of tomorrow. Any user should be able to activate them (or not) without any kind of privilege. It's like requiring administrator privileges to let your browser interpret HTML! Come on it's time to evolve and accept that RIA technologies are part of the web as much as HTML is.

Secondly, before discrediting a technology: Have you tried it? Have you explored its possibilities? Silverlight is a young technology that needs to be matured, however you would be surprised to see what it can do considering its age. It's already a serious Flash/Flex competitor and I wouldn't be surprised if it becomes the leader of the RIA market.

I'm not a Silverlight freak, actually I've been using Flash and Flex for a long time. But it doesn't prevent me from trying the new stuff coming out. It's not always good but at least I give it a chance! Let's stop being so narrow minded please...
