Sharepoint Installation
I have installed Virtual Box( With Windows Server 2008 R2 Standard-Enterprise-Datacenter-Web with SP 1 Debug/Checked Build 64-bit) on Windows 7. While installing prerequisites , I found that in IIS Server, there has been a Conifguration error, and the installation of Windows Identity Foundation, Windows Chart Controls have been skipped. So, when I tried to manually install Windows Identity Foundation, I got an error saying " Update is not applicable on your computer".
