Could not uninstall Net framework 4.5.1
2014-07
When I tried to uninstall framework 4.5.1, I got this problem as shown by this picture
I had tried Net CleanUp, but the problem still remains. In my computer, I already installed framework 4 and the latest version 4.5.1. My computer had experienced system restore and cause this problem occurs. From now, I cannot open framework 4 applications even I already installed on my computer. What I want is uninstall all the frameworks but I could not do for framework 4.5.1 but 4.
I have an English Windows 7. For some reason I think I installed a Dutch Language pack for .NET. I'm a C# web developer and now all error messages in my web applications are in Dutch (at my PC). How do I tell .NET to show English errors to me, or how could I delete the language pack?
I've looked in Control Panel / Program and Features (and installed updates) and I tried Turn Windows Features on or off, but I could not find a way to uninstall the Dutch .NET language pack.
In the end it seemed as easy as uninstalling the Dutch windows 7 language pack.
