I have attempted to download & install Microsoft Silverlight. The missing file is the .msi (installation pkg) & it asks to insert the cd. I do not have the cd, probably downloaded online and later attempted to delete program. When I try to run uninstall I get the same window asking for the cd. When I try again, I get the same msg for the install disc. This is on Win 7 and IE11, Safari, Chrome. Thank you.
