AcuityMaster for Windows
The desktop edition is discontinued. Existing customers can still download it.
No new trials are being issued for the Windows edition
The AcuityMaster Windows desktop edition was discontinued on 4 August 2026. It is no longer sold, no longer updated, and trial licenses are no longer issued for it. If you arrived here from an old link or bookmark, that is why.
AcuityMaster Cloud is the current product. It runs in a browser on Mac, Windows and iPad — nothing to install — and covers the same charts. Start a free 7-day trial, no credit card required.
Already running the Windows edition?
Your license keeps working and we are still supporting it. If you need to reinstall — a replaced workstation, a rebuilt machine — enter the email address on your account and we will send you a download link.
Not recognised? Ask Mark directly
If the address on your account has changed, or you were not the person who originally bought it, the automatic check will not find you. That is a limitation of our records, not a judgement about you — use this and Mark will send the installer himself, usually within a day.
