My windows 7 system had .Net Framework v. 4.5.1 installed and windows update notified me of a security update. Every time I try to install it, it fails with an error code 643. I did some googling and found a couple of things, including a Microsoft Fix-It (that didn't work) and a .NET Repair tool (that didn't work). So I went and uninstalled it completely. Then windows update shows an update available of course, the .NET 4.5.1 so I re-installed and it failed the install. When I re-boot I get an error saying I need to install .NET 4.0.30319.
what's going on? Why does it keep failing the install?
