Solition to Runtime-Error of VC++:"application has failed to start because msvcr80.dll not found"
After installing OpenCV, when I ran one opencv program, an error occured “application has failed to start because msvcr80.dll not found”. The build is OK; the error is runtime. And this error only appeared in debug mode.
One solution is to change the property of project as follows (in Debug configuration),
Property -> Configuration Properties->C/C++ ->Code Generation->Runtime Library-> Change the value “Multi-threaded Debug DLL (/MDd)” to “Multi-threaded DLL (/MD)”.
