If you have an older Athlon CPU Silverlight will not install. The CPU must
support the entire multimedia extensions or something. I forgot the exact
rdetails but that was the context I discovered with an XP Pro machine I had
that Silverlight would not install on. If this may be pertinent you may be
able to upgrade the BIOS that will install the multimedia extensions. I
missed by one rev release.

>I have been trying to install Silverlight KB955305for some time but keep
getting Error 0x5DF. It downloads OK but will not install. Every other
MS
and Windows Updates install OK except this one. I run XP Pro SP3 with all
current updates installed. I'm not completely computer literate but I saw
another post somewhere where someone else had the exact same problem but I
can't find it again.
