Popping up error message that uninstalls Microsoft frame network .NET

Hi experts,
For patching beta, I was in need to start my computer on a whole night. In the morning, I found an error message, telling to install the latest C++ and I got the same done. Then, another error message that uninstall Microsoft frame network .NET popped up. I also got the same uninstall, but still, I am not in a position to work on it.
Do you have any idea regarding this issue? Please help me.
Thanks in advance.
