I'm trying to install .NET 4.0 on some VMs using dotNetFx40_Full_setup.exe and am getting error 0x800C0005. The issue likely involves the firewall/proxy/security configuration. Rather than dealing with that, does Microsoft have an offline install available yet? I've searched but not found one.
A page containing downloads for all the .NET offline installers can be found at http://www.microsoft.com/net/download. It includes downloads for the full framework, client profile, x86, x64 and IA-64.
