I\'m trying to run an application that I\'ve recently developped onto another computer and which I\'ve compiled using VS2013.

Running it I get:

When I encountered a similar problem, first installed the VS 2013 C++ redistributables vcredist_x86.exe and vcredist_x64.exe (https://support.microsoft.com/en-us/help/3138367/update-for-visual-c-2013-and-visual-c-redistributable-package), then I determined what dependencies the file had:

c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin>dumpbin.exe /dependents "C:\Temp\MyLibrary.dll"

Microsoft (R) COFF/PE Dumper Version 9.00.30729.01

  Summary

        5000 .data
        2000 .nep
        1000 .pdata
       4E000 .rdata
        1000 .reloc
        1000 .rsrc
       10000 .text

c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin>

Next I searched the registry and it did not find mfc120d.dll, only mfc120.dll and mfc120u.dll (see https://serverfault.com/questions/576831/how-do-i-know-if-a-dll-is-registered), so instead of using the debug version I switched to the release version which uses mfc120.dll and the application worked.
