Before installing, consider these important points:

1st. AutoCAD 2021 is not compatible with Windows 7, which has lost Microsoft's technical support. It works with Windows 8, but it is highly recommended that you update to Windows 10.

2nd. The software is not compatible with 32BIT systems; AutoCAD 2019 is the latest version that supports 32BIT. Starting from AutoCAD 2020, all versions are only compatible with 64BIT systems.

3rd. For a trouble-free installation, ensure your operating system is up-to-date, virus-free, and includes necessary Windows PC add-ons:

  • Net Framework 3.5 Enabled
