been there, tried that.

I did find a workaround after posting my message.

workaround:

found it here after doing a google search: your operating system does not support the 64-bit setup of silverlight : The Official Microsoft Silverlight.NET Forums

quite vexing, given all I use silverlight for is the xbox website....

Hi

Thanks for the light, it worked, I now have an up-to-date version 5 of Silverlight.

The forum link provided is very useful. Indeed the final solution is installing through the extracted msi and msp files from the downloaded End-User Runtime for Windows (64 bit) (http://go.microsoft.com/fwlink/?LinkId=229321 "Silverlight_x64.exe").

The aforementioned windows installer files are "silverlight.msi" and "Silverlight.msp" which you can find in "Silverlight_x64.exe" by using 7-Zip.

However the measurement works for me on my Windows Vista Enterprise x64 where installing from either the downloaded executable or the extracted install.exe fails.

Since it is not a clean installation that I have installed and then uninstalled the x86 version of Silverlight beforehand, perhaps fiddling with the x86 one first is a prerequisite. f*ck Microsoft!
