Getting 1638 on Silverlight upgrade, can someone help?
I recently jumped into testing installing via GPO - I have everything on its own policy including silverlight. A new version recently comes out, but if I try to deploy it (or for that matter, run it directly) I get a 1638 already installed error. I set it up as an upgrade to the previous software installation and even requested that the prior version be uninstalled but it still does not appear to work. Would appreciate any help.
