This means that you have two different version of CRT linked. Are you using any static or dynamic libraries? They need to have same version of CRT. -Saurabh

[Chris Losinger]

one or more of the static libraries you are linking to has been built using a different C-runtime version than your main application. check the project Properties / C/++ / Code Generation, and look at the "Runtime Library" setting. they must all match. -c

Both LIBC.LIB and msvcrt.lib are used, which may cause error. Project Settings: -> Configration Properties -> Linker -> Input -> Ignore Specific Library: libcmtd
