The software is free to download and install. REX Accounts runs as a full trial for 60 days with a trial key sent by email; Paperworks and Visio2DXF have no trial: they are licensed to one named user and ask for your name and licence key the first time they run. Nothing is uploaded from your machine, ever.
Free 60-day trial: request a trial key, install, tick the licence agreement, enter your company name and the key. Nothing you enter is lost when you buy.

Installer (recommended): run the Setup.exe, click through, and you get a Start-menu entry, a Desktop shortcut and an Uninstall entry in Windows Settings. Accounts and Paperworks install for your user only (no admin needed); Visio2DXF asks for admin because it also sets up the free LibreOffice engine for legacy .vsd files. Windows SmartScreen may show "Windows protected your PC" the first time: click More info, then Run anyway.
Portable zip: right-click the zip, Extract All, open the folder and double-click the REX … .exe (or Create shortcuts.cmd once for shortcuts). Nothing is installed; delete the folder to remove it.
Double-click the zip, then drag the REX … .app into your Applications folder. The apps are signed but not yet notarised with Apple, so the first start is refused with "Apple could not verify … is free of malware". On macOS 15 and later: close that message, open System Settings > Privacy & Security, scroll down to Security, click Open Anyway next to the app's name, confirm with your password, then Open. It opens normally from then on. On older macOS: right-click the app, choose Open, then Open again. If you prefer Terminal: xattr -dr com.apple.quarantine "/Applications/REX Paperworks.app" (same for the other two apps). To uninstall, drag the app to the Bin.
REX Accounts: tick the licence agreement, enter the company name exactly as in your trial or purchase email, then the key. When you buy after a trial, enter the
purchased key under Settings, Licence, and carry on.
Paperworks and Visio2DXF (one named user, no trial): your key arrives by email when you buy. In the program enter your name exactly as it appears in that email (and your company if you want it shown), then the key. Activation is offline. Keep the email: to reinstall, or to use a second computer of your own, you need the same name and key.
Paperworks OCR (making scanned PDFs searchable) is built in on Windows; on macOS install the free Tesseract engine. Visio2DXF converts legacy .vsd files with the free LibreOffice; modern .vsdx files need nothing else.
