Matlab Compiler Excel Add-In MCR Instance Error

Hello, I am working with MATLAB 2017a and testing a trial for MATLAB Compiler. I just created a very simple m function as below

function val=myfun(a,b) val=a+b

and packaged by using the Library compiler. In excel file, I've imported the myfun.bas created in the folder ../myfun/for_redistribution_files_only

but when I use the myfun() function from excel, I got this error:

Error in myfun.Class1.1_0: MCR instance is not available

I ran correctly the MCRInstaller before using the Library Compiler.

Any suggestion how to solve the issue? thank you Best regards, Paolo Tarpanelli

Does this link help to solve your issue?

Hi Paolo and Kojiro, I also have the same issue. This link did not help. Does anybody have another solution? I have 64 bit Excel and MATLAB.

[Kojiro Saito]

Could you provide more information?

• Which MATLAB version?
• The MATLAB version where you compiled MATLAB scripts to Excel Add-in is the same version of MATLAB Runtime (or MATLAB) you're running the Excel Add-in? And both are 64 bit editions?

[Vadim Shabelnikov]

MATLAB R2016b (9.1.0.441655) 64-bit (win64). MATLAB Component Runtime (MCR) 9.1, MATLAB Compiler 6.3 Both are 64 bits, and I'm running and compiling at the same machine with the only version of MATLAB.
