Simulink coder ert not working

I have a simulink model that I would like to export to C++ using the coder add on. I need the target to be set to ert.tlc. However whenever I change this setting in the configuration settings then try to open the coder app, I get the following message:

'Current system target file is set to "ert.tlc". Do you want to change the system target file to "grt.tlc", and open Simulink Coder App?'.

Then I am forced to change the target to grt.tlc, otherwise I cannot make the export. Are there some other settings that I need to change to allow the export to ert.tlc to work?

You need the "Embedded Coder" toolbox to generate code for embedded real-time target.
