Got a brand new Windows 7 64 bit machine for my mapping. Wanted to download ArcGIS Explorer Desktop but it requires downloading of Microsoft .NET Framework 3.5 Service Pack 1. Went to the Microsoft website and it turns out that that does not download on anything higher than Windows XP. Framework 4 does, but does not have the components of 3.5. Sooooo since ArcGIS Explorer desktop supposedly works in Windows 7 64 bit, how exactly do I make it install????
