We suspect that Hyper-V is still enabled. Try the following steps:
(1) Make sure that you have restarted the computer after disabling the Hyper-V settings in the Windows feature list.
(2) After the restart, run the "systeminfo" command from Windows Command Prompt (CMD) or from MATLAB:
>> !systeminfo
In case Hyper-V is still enabled, you will see the following output:
Hyper-V Requirements: A hypervisor has been detected. Features required for Hyper-V will not be displayed.
Try to repeat the steps from the troubleshooting guide to disable Hyper-V. Again, make sure to restart your PC:
(3) You may also have to disable additional features that use the Microsoft virtualization technology, for example:
* Windows Subsystem for Linux
* Windows Hypervisor Platform
* Virtual Machine Platform
(4) Some of our customers reported that disabling Intel Virtualization support in the BIOS resolved the issue. See the following link for more info:
(5) We are aware of cases where disabling Hyper-V in the Windows feature list will not work, even after multiple attempts, and the Hyper-V feature will still be shown as enabled by "systeminfo". In this case, contact your IT helpdesk to disable Hyper-V on your machine.
(6) If your company's IT policies do not allow disabling Hyper-V, then you will not be able to use Simulink Desktop Real-Time on this machine. Our recommendation is to talk to your IT helpdesk to get access to an "offline" machine that does not have to follow the company's IT policies. Also, note that other hypervisors such as VMware Workstation will work with Simulink Desktop Real-Time.
