A Windows installation includes a copy of the msvcrt.dll file so at least you have the file on your system.
The error is telling you that WWE is looking into msvcrt.dll for a procedure called get_current_locale (if that is correct) and not finding that procedure in the msvcrt.dll file that is on your system. That usually means it is the wrong version of the file.
Those files are part of the Microsoft Visual C++ Redistributable Package and looking around the whole Internet I think WWE needs the 2010 version which may not be installed on your system. Another place says it should be included with WWE so who knows. BossDweeb would know but where is he when you need him.
You can look in your Control Panel, Programs and Features to see what versions of C++ Redistributable you have installed and you may have several because one third party developers may use a certain version and another developer may use another version. You can see this system has several versions of C++ Redistributable installed (which is fine):
Each package has different versions of files and they have the same name so how can this be? Windows has figured out a way to allow different versions of file with the same same to be on your system at the same time using WinSxS (Windows Side by Side) technology.
Since you did not specify your OS details (x86 or x64) and the MS Answers implementation is too stupid to ask for fundamental system information when a new question is asked you need to download and install the one that is right for your system and I would start with the 2010 version since that is what I read in another forum:
x86

x64

After installing restart your system and see how things look.
It could be that you need a different/another version of C++ so you might google something like this and see what you can find:

If you still have the issue and since your issue is not with Windows 7 (this community) but your issue is with your game you will probably get the best support from the WWE gaming community.
