An IT specialist had to sort the issue for me. It turns out it was something to do with the microsoft .net framework 4.7 update that windows installed. He reverted back to version 4. I'm not sure if he had to do anything else to restore the system but it works fine now. He has just advised me not to install that update.

There are not "several causes" of the error message.

There is one cause of the error message.

Here is what is means:

Search your system for MSVCR120_CLR0400.dll and when you find it check the Properties like this example:

What is the version on your system?

Whatever the version is, write it down and then come back and tell us what it is.

The files get installed with the C++ 2013 Redistributable package and is not part of a Windows installation so it is doubtful sfc  /scannow will help you.

Inside these DLLs are functions and the programs that are complaining are telling you that they are not finding the nextafterf function inside the MSVCR120_CLR0400.dll but as you can see on my system with my installed version of the file it is in there:

Apparently your MSVCR120_CLR0400.dll is afflicted, the wrong version or something else is not right about it.

But as usual we know nothing about your environment...  are you a home user, a corporate user connected to a corporate network or something else?  Maybe there is a reason you have that version of MSVCR120_CLR0400.dll on your system.

First make a System Restore point so in case things get worse you can undo the changes.

If you are a home user you can check your Control Panel, Installed Programs, find the C++ 2013 and uninstall it:

After uninstalling restart your system and if there are more errors that are DIFFERENT, post them too.

Then download and install (in your case) the 64 bit version from this link:

https://www.microsoft.com/en-us/download/details.aspx?id=40784

Then restart your system and check the version of the file again.

If it still doesn't work, tell us the original version you wrote down, and the version you just installed.

In your example error SelfService.exe (and Skype) are not Windows programs so it could be that there is something wrong with them too.

    In our company this issue is affecting us a lot lately, we don't know how this happens, but there are two bad DLL library files with the same name, that end up randomly on our users machines.

    The files two files are located in the following folders:

    C:\windows\system32

    C:\Windows\SysWOW64

    The bad files not only are smaller in size than the good ones (having 255, respectively 296 less function definitions), but they have also renamed functions i.e. preceded with an underscore or even more (see attached image), which is why the entry points can't be found:

    **Bad file:**C:\windows\system32\msvcr120_clr0400.dll => 850 KB (255 less function definitions)

    **Bad file:**C:\Windows\SysWOW64\msvcr120_clr0400.dll => 856 KB(296 less function definitions)

    The simplest and fastest solution that we found for fixing this issue, is to keep a pair of good DLL libraries at hand, and simply replace the two bad files with the good ones (make a copy from an unaffected machine):

    **Good file:**C:\windows\system32\msvcr120_clr0400.dll => 9 71 KB

    **Good file:**C:\Windows\SysWOW64\msvcr120_clr0400.dll => 965 KB

    Besidethis related case about Skype, we found out that these two files affect the SCCM Software Center and the Bentley Connector with that message "The procedure entry point nextafterf could not be located in the dynamic link library MSVCR120_CLR0400.dll", as well as Autodesk products like all AutoCAD versions and all verticals with a FATAL ERROR up front.

    After replacing the two files, everything goes back to normal,

    Hope this helps,

    Constantin
