Aspen Hysys: System Requirements

A stable Local Area Network (LAN) or a secure Virtual Private Network (VPN) connection to your organization’s license server is required to open the software.

If working remotely, a high-speed VPN connection is required to check out a license from your company's server, or you must "commute" (borrow) a license for offline use before disconnecting. Summary Checklist for Buyers

If you plan to link HYSYS with Microsoft Excel, Aspen Plus, or specialized third-party plugins simultaneously, 32 GB is highly recommended.

NVMe M.2 SSDs are highly recommended over standard SATA SSDs. Space Required: Aspen Hysys System Requirements

64-bit is strictly required. 32-bit operating systems are completely unsupported by modern versions of AspenTech software.

AspenTech uses an SLM server to distribute seat licenses. Your workstation must have a stable network interface card (Ethernet or reliable Wi-Fi) to communicate with the license server.

AspenTech software is not lightweight. A full suite installation requires surprising storage. A stable Local Area Network (LAN) or a

Aspen HYSYS is not a 3D rendering engine, but modern versions feature advanced 2D and 3D PFD (Process Flow Diagram) layouts, hydraulics visualizers, and safety analysis graphics. Integrated Intel Iris Xe or AMD Radeon graphics.

Before you click "download," it is critical to understand that running a steady-state simulation is vastly different from running a dynamic simulation or an integrated workflow. Installing HYSYS on an underpowered machine leads to simulation crashes, slow convergence, and lost productivity.

RAM is arguably the most critical component for handling large, complex simulations. Insufficient memory leads to excessive disk swapping and severe slowdowns. NVMe M

is the baseline for professional engineers handling medium-sized plant designs.

: Microsoft Edge, Google Chrome, or Safari (typically required for documentation and license management).

AspenTech no longer publishes a single, static system requirements document. Instead, the company now maintains detailed for each major software release. The most reliable source for the latest information is the official AspenTech "Platform Support" portal, which details tested hardware, operating systems, and virtualization environments. This is the definitive guide, as it is updated whenever platform requirements change.
