From the comments, the problem was caused by using dlls that were built with Visual Studio 2013 in a project compiled with Visual Studio 2012. The reason for this was a third party library named the folders containing the dlls vc11, vc12. One has to be careful with any system that uses the compiler version (less than 4 digits) since this does not match the version of Visual Studio (except for Visual Studio 2010).

• vc8 = Visual Studio 2005
• vc9 = Visual Studio 2008
• vc10 = Visual Studio 2010
• vc11 = Visual Studio 2012
• vc12 = Visual Studio 2013
• vc14 = Visual Studio 2015
• vc15 = Visual Studio 2017
• vc16 = Visual Studio 2019

The Microsoft C++ runtime dlls use a 2 or 3 digit code also based on the compiler version not the version of Visual Studio.

• MSVCP80.DLL is from Visual Studio 2005
• MSVCP90.DLL is from Visual Studio 2008
• MSVCP100.DLL is from Visual Studio 2010
• MSVCP110.DLL is from Visual Studio 2012
• MSVCP120.DLL is from Visual Studio 2013
• MSVCP140.DLL is from Visual Studio 2015, 2017 and 2019

There is binary compatibility between Visual Studio 2015, 2017 and 2019.
