I'm changing my PC, do I need a new license?

xlCompare license is bound to your PC. If you've upgraded your PC - changed HDD, RAM, ... you can use existing activation key you have.
The activation key for your PC is stored your account in the Spreadsheet Tools Customer Service. To get this key you need to login to your account and just copy key string from the Activations page into xlCompare.
If you've replaced your PC with a new one - you need a new activation key.
Login to your account, and remove the Activation Key you don't need on the Activations Tab.
When key is removed you can select xlCompare on the top of the page. This means that you have available Activation Key for this product.
Now you can install xlCompare on your new PC and activate it by entering your login and password.
