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.

    Dear All,

    I am also experiencing this same issue, also since a windows update. I have tried all the suggestions on here but with no luck. Here are the details I can share.

    • operating system - Windows 7 professional
    • software causing the issue in my situation - WD smartware (western digital software for backups)
    • Error also relates to nextafterf in the MSVCR120_CLR0400.dll
    • I have confirmed that nextafterf is actually missing (using the methods above)
    • I have removed and re-installed the relevent Microsoft visual C++ programme
    • I confirm that before and after this the version of MSVCR120_CLR0400.dll remained the same as 12.00.53315.36315

    I have contacted Western Digital last week but had no response.

    Any further advice how to restore the dll file or reinstate nextafterf?

    Thanks
