We take a generous and realistic attitude toward multiple installations. All Hagel Technologies products may be installed on more than one personal computer(s), such as desktop and laptop, or two desktops used essentially by the same person, or for multiple users on a single personal computer, but not both. If the computers you wish to install it on are primarily for personal use by a single individual, a single license will suffice.
Like most other software, however, if these computers are being used by different people, then a license is required for each installation. We offer a deeply discounted Family Pack license which allows you to install TweakMASTER on up to 5 computers in one household.
