Are local admin rights required to install Silverlight?

Can anyone provide an emphatic answer as to whether local admin rights are required to install the Silverlight 3 client? Most of the Google results say “yes” (with some conflicting answers), but I’ve just tested this on several Win XP machines and installation was definitely successful without admin rights.

Just开发者_运维技巧 to be crystal clear, the machines I’ve tested are in a corporate managed desktop environment and users most definitely do not have local admin rights. A “net localgroup Administrators” command confirms they’re not in this group.

Can anyone absolutely confirm either way? Thanks.

Yes, local administrative rights are required.

Admin rights are required. By default XP users are local admins.
