Hi Grigory,
Can you check your PATH variable to see if the MCR path to mclmcrrt7_14.dll is ahead than the path to the corresponding version of MATLAB?
For MATLAB R2011a 64-bit MCR, the default location of the MCR will look like this: C:\Program Files\MATLAB\MATLAB Compiler Runtime\v715\runtime\win64;
If you have installed the MCR somewhere else, it will be in: mcrroot\runtime\$arch
The term mcrroot stands for the installation path of the MCR and $arch stands for the architecture of the computer. For windows, the values of $arch will be win32 or win64.
