I tried to build a standalone app and it keeps aborting due to "Rapid accelerator mode" errors. Error generating the app Caused by: Unable to build a standalone executable to simulate the model 'TestBuild2' in rapid accelerator mode. Error(s) encountered while building "TestBuild2"

How do I disable rapid accelerator mode so I can build an exe from simulink?
