A Finance licence allows you to use Rainbow Pro to develop and review your own spreadsheet models (like the Business licence), and in addition it entitles you to provide a service developing and/or reviewing models for others.
On receipt of your order, we will send you (normally within one working day) a licence key that will enable you to convert your free-trial copy of Rainbow Pro into a fully-licensed version. The licence will entitle you to support and updates for 2 years from the date of purchase, and after this you will still be able to continue using the same version of Rainbow.
Once you have received your licence key, go to the Rainbow tab in Excel, click User Guide and About Rainbow, then enter (copy and paste) your licence key plus your name and email address on the registration form. Click OK and follow the prompts, and Rainbow will display confirmation of your licence details.
