Error trying to launch QEMU

I'm trying to follow the tutorial on https://www.mathworks.com/examples/embedded-coder/mw/armcortexa_product-arm_cortex_a_gettingstarted-getting-started-with-embedded-coder-support-package-for-arm-cortex-a-processors

But when I try to run codertarget.arm_cortex_a.runQemu() I get an error:

Error using codertarget.qemu/launchQemu (line 116)
    Unable to launch application in QEMU. System returned:
Error in codertarget.qemu (line 70)
    this.launchQemu();
Error in codertarget.arm_cortex_a.runQemu (line 106)
    qemu_obj = codertarget.qemu(argStr);

I have the QEMU and ARM Cortex A support packages installed. I even tried installing QEMU separately in Program Files to no avail. What am I missing?
