I have matlab script compiled as net assembly or .dll. When i use development server which mean built in server on visual studio, the program works fine without error, meanwhile i deployed on IIS , the program fails to execute matlab code with this screenshot error message. enter image description here

Answer 1

I have two suggestions:

1) Check that the server OS and IIS version is also 64-bit like your VS 2015.

2) Check that the MATLAB Compiler Runtime ('MCR') is installed (must be same version as your MATLAB).
