I am trying to download an application from github that utilises MATLAB runtime. the application is called SeabORD v1.2 which was created using MATLAB R2017a and that I must install the appropriate version of MATLAB Runtime, which is 9.2.
SeabORD/ at main · MarineScotlandScience/SeabORD · GitHub
The application will download MATLAB Runtime from the web, and when SeabORD is installed for the first time, MATLAB Runtime will be installed if required.
I am therefore getting the above error with the additional text:
"Call to download server failed (HTTP error code: 403). Try to rerun the installer. If that fails, please check your internet connection, firewall, proxy server or virus scanner settings".
It is not however my internet connection or firewall or proxy server or virus scanner settings thats causing the issue. I googled this issue and got directed to the matlab website Q and A hence why i am gathering tis a matlab issue and that my program is having issues downloading due to pulling MATLAB runtime from the web to try and install. Without MATLAB runtime i cannot download seaBORD which i need for my work.
Has an update or something caused a problem to arise with MATLAB? This is urgent and hence i need help fixing this.

Hi Andie,
The workaround suggested by the MathWorks techinical support is to replace 'https://' with 'http://' for the MATLAB runtime download links. (refer to this thread). Since your application is created using MATLAB R2017a, you can get the corrosponding download link for MATLAB runtime 9.2 here: https://mathworks.com/products/compiler/matlab-runtime.html
To address the issue, you can create an environment variable named 'MW_INTERNAL_INSTALL_AGENT_URL' with the value set to the corresponding download link, using 'http://' instead of 'https://'. In your case, it would be: 'http://ssd.mathworks.com/supportfiles/downloads/R2017a/deployment_files/R2017a/installers/win64/MCR_R2017a_win64_installer.exe'
This solution should resolve the issue. If possible, you could also consider recompiling the application using MATLAB R2020b or a later version.
Hope this helps!

@Andie Have you had the chance to set the environment variable using the value I mentioned?
You can do this by going to 'Settings' > 'System' > 'Advanced System Settings' (below device specifications) > 'Environment Variables'. Then, click 'New' in either the User or System variable section, as needed. Set the 'Variable Name' to MW_INTERNAL_INSTALL_AGENT_URL and the 'Variable Value' to http://ssd.mathworks.com/supportfiles/downloads/R2017a/deployment_files/R2017a/installers/win64/MCR_R2017a_win64_installer.exe
