The SCCM client installs Silverlight x86. The http://www.microsoft.com/silverlight/ page gives me the x64 version when I download it
Interestingly if you have an OLDER version with the x64 flavor, the newer x86 flavor included with the sccm 2012 R2 client will not install. Have any of you encountered this yet? Getting really sick of this poor programming :-(
