Cannot reinstall Microsoft .NET Framework 4.5 or 4.51

I am using Windows 8 and I uninstalled Microsoft Frameworks 4.5 and 4.51 because a blog suggested reinstalling these if I had issues debugging in Visual Studio. I uninstalled them in the control panel in the programs and features section. I downloaded the web install frameworks for both from Microsoft's site, but when I run them, I get a message that says "The .net framework 4.5 and this update are already installed on your computer".

I tried a .net cleanup utility, but it says "ERROR Cannot remove product '.NET Framework 4.5' because it is not allowed on the current OS"

I uninstalled the following from the control panel:

  • Microsoft .NET Framework 4.5 Multi-Targeting Pack
  • Microsoft .NET Framework 4.5 SDK
  • Microsoft .NET Framework 4.51 Multi-Targeting Pack
  • Microsoft .NET Framework 4.51 Multi-Targeting Pack (ENU)
  • Microsoft .NET Framework 4.51 SDK

I am not sure how to re-install the .net frameworks or if there is another place I need to go to remove .net framework 4.5 completely before reinstalling it.

Any suggestions would be appreciated. Thanks

The things you uninstalled seem to only be from the SDK, not the framework itself. I suspect the framework cannot (easily) be removed. – Joachim Isaksson
.NET 4.5 cannot be uninstalled from Windows 8. In order to reinstall, you need to refresh Windows 8 PC. Could you share blog post that recommends reinstalling? – Varun
I am wandering what is the difference between contents in Multi-Targeting Pack and Multi-Targeting Pack (ENU/english) – Junior Mayhé

I learned that Visual Studio 2013 comes pre-installed with .net frameworks 4.5 and 4.51. The company I worked for already had this installed. I was going to reinstall it, but I did a repair first by selecting VS 2013 under programs and features and selecting repair. 4.5 and 4.51 are now installed again.

The debugging issues I had (application not stopping at my breakpoint correctly) had something to do with JustMock profiler being enabled. I have disabled this for now.
