I learned Silverlight4 was out of date thanks to Secunia. I tried to install version5.
Although version4 has been succesfully uninstalled, I cannot install the 5.
My system cannot accept 64version of Silverlight, it says.
Frequently Asked Questions
But I have a 64 version of Vista, Firefox and Chrome and IE all are perfectly up-to-date.
I therefore wonder: why doesn't it work?
please someone help me...
