Aspen Hysys System Requirements -

Required for "Export to Excel" features and report generation.

: If using a VM (e.g., on a Mac), ensure you allocate at least 4 cores and 8 GB of RAM to the virtual environment. Aspen Hysys System Requirements

Aspen HYSYS is built exclusively for the Windows ecosystem. It does not natively support macOS or Linux. V8.7 aspenONE Minimum Hardware Requirements - AspenTech Required for "Export to Excel" features and report
