I often get asked about how to perform silent and unattended installs for various versions of the .NET Framework. In order to hopefully make things easier to find going forward, I decided to create a single blog post with information about silent and unattended installs, repairs and uninstalls for each shipping version of the .NET Framework.

Net Framework Client Profile Download
Microsoft .net Framework 4 Client Profile X86 And X64 Free Download

The Microsoft.NET Framework 4.0 full installer (32- and 64-bit) is 48.1 MB and the Client Profile installer is 41.0 MB. The extracted installation files are 237 MB and 194 MB respectively, and once installed, they are 537 MB and 427 MB. Seems that I'm stuck in a loop. I dont have the.NET Framework 4 Client Profile installed yet so I downloaded it from Microsoft. However, Windows 7 wont let me install the Client Profile until I've removed the.NET Framework 4 Extended.

The command lines listed in this blog post do not apply to versions of the .NET Framework installed as a part of the OS. You can refer to this blog post for a list of which version of the .NET Framework ships with which version of Windows.

Note - if you try to repair or uninstall the .NET Framework and setup fails, you can try to use the .NET Framework Repair Tool to solve the problem.
