1. You are on wrong place. This is support forum and neither MS support not download site.
2. Try to get installation media from appropriate supply channel.
3. Microsoft has changed its direct download sites, but resources are giving unreliable references:
Important Note May 2014
Microsoft is retiring the previous download servers msft-dnl.digitalrivercontent.net, msft.digitalrivercontent.net and azcdn01.digitalrivercontent.net. All downloads are moving to the Azure storage on drcdn.blob.core.windows.net. We have
updated all links, so the files should be reliably available again.
