Is there a way to bypass including the MCR and downloading the MCR in your package and still be able to build a package in R2014b?

I am running my deployable application on a closed network. I do not want it to download the MCR from the website nor do I want it to include the MCR in the executable. However, the application compiler will not allow you to package if neither of these options are selected.

Hi Tommie,

MCR (MATLAB Compiler Runtime) is required to be installed on the machine on which you deploy the application. This is because, the machine on which you deploy typically does not have MATLAB installed, and MCR has all the libraries needed to run the compiled MATLAB code. Thus, you can view MCR as MATLAB without a GUI. For more info on MCR, visit this page

Given this fact, the reason why MATLAB compiler gives you only these two options is:

Option 1: Runtime downloaded from web: If you do not wish to include MCR as part of your compiled application, you can let users download it from the web, which makes the compiled application size ~ 5 MB

Option 2: Runtime included in package: If you wish to include the MCR as part of your compiled application, you can choose this. But, it will make the size of the application ~ 800 MB.

Hope this helps,

Abhiram.

We also have this problem. The client already has MCR installed on their machine. We do not want to include either the web link or the MCR in our COM object, however the matlab library compiler front end does not allow you to exclude the MCR from the COM object.

When we choose the "download from web" option the package fails as it cannot access the mathworks web site.

We have the same issue. It is a hassle to get IT to allow installing the MCR for each user, but this only needs to be done once.

The problem is that even after MCR is installed, every time we want to deploy a new version of the compiled app, it still asks for admin rights only so it can install the MCR, which is already installed.
