. Versions released from 2020 onwards generally require Windows 10 or 11. Resource Requirements : At least is needed for basic tasks, but is highly recommended for complex simulations or Simulink. Disk Space : A typical installation requires roughly 10GB–32GB depending on the number of toolboxes included. If a host machine blocks execution entirely, it
Summary
If the portable version asks for activation, you will need to re-activate using a valid license file. Conclusion Run them on the host machine before launching
If you only need to run compiled apps, not develop them, is a better, officially supported option.
To run MATLAB on a Windows 7 64-bit system, make sure your computer meets the minimum system requirements:
