Below are the recommended and minimum system requirements to install and run Altium Designer.

Recommended System Requirements
- Windows 7 SP1 (64-bit only), Windows 8 (64-bit only), or Windows 10 (64-bit only) Intel Core i7 processor or equivalent
- 16GB RAM
- 10GB hard disk space (Install + User Files)
- SSD
- High performance graphics card (supporting DirectX 10 or better), such as GeForce GTX 1060/Radeon RX 470
- Dual monitors with 2560x1440 (or better) screen resolution
