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.

    Good job.

    Of course I have 4.7 installed at the moment.

    Now I am thinking about what to do and how to figure this out if it comes up again...

    Earlier you said:

    • I have confirmed that nextafterf is actually missing (using the methods above)

    So after going back to 4.0 were you able to (using the methods above) peek inside the MSVCR120_CLR0400.dll and find that nextafterf is in there?

    Will you post a screenshot of the details of the MSVCR120_CLR0400.dll that works?

    Click for instructions on How to include a screenshot in your post

    It should look something like this (but probably a different version):

    Hello, so,

    I can confirm that the previously relevent dll file does NOT contain 'nextafterf' so it appears that may have been a wild goose chase. Here is a screen shot of the properties.

    Hmmm...

    With Windows it is possible to have files of different versions with the same name on your system as long as they are in different folders/directories.  Sometime the third party application installations will bring along with them the files they need and put them in the right place and NOT replaces the Windows versions normally found in system32.

    The applications that use the files know which version they are supposed to use and where they are supposed to be so they will get the file that is right for them.  It would seem reinstalling those apps would fix things if their copies got replaced.

    There is only one copy of that file on my poor system:

    Perhaps those applications like your WD SmartWare are installing their own version of MSVCR120_CLR0400.dll tthat they need and using that copy instead of the one in system32.

    I wonder if your system has some other copies of MSVCR120_CLR0400.dll somewhere.

    I would have to install some of those other programs to see what they are doing and don't really fell like it at the moment.

    Oh well - I was just trying to be me and understand more about what is going on so it makes sense.
