This runs on any of your computers and requires an internet connection to start up.
From version 3.5.3 you can have both online (any computer) and offline (linked to hardware) installed with separate desktop shortcuts.
Offline editions are linked to hardware you own, which may be your computer, which can be changed, or a USB key.
Linking to a computer avoids needing a USB key, and when you upgrade to a new computer that can be enabled in the same way. To register: run the online edition, go to the Info page, click 'Enable offline', and email us for a download code for this computer. Uninstall any USB key version first before installing a computer linked version, in Windows Settings → Apps.
Alternatively order a USB key that allows you to be offline on any number of computers, each computer requiring the key to start the program. To install the USB key edition first uninstall any computer linked edition as above. For the latest purple body USB key Windows will automatically install a driver, either before or after you install the software. Plug it in, and after the "We're setting up Sentinel HL" message wait around 10-20 seconds for "Device is ready, Sentinel HL is set up and ready to go". Then run the installed program. On Windows 8 there's instead a progress icon on the Windows taskbar. The black, or black and purple USB keys have their driver included in the application installation.
