A Business licence entitles you to use Rainbow Pro to develop and review your own spreadsheet models, but not to provide a service developing or reviewing models for others (please purchase a Finance licence if you wish to use Rainbow for this purpose).
An update licence is available if you have a current licence for Rainbow Pro version 8.0 or later (with a licence key based on user or company name and email address). On receipt of your order, we will send you (normally within one working day) a licence key that will enable you to add one year of support and updates to your current licensed copy of Rainbow Pro.
Once you have received your licence key, go to the Rainbow tab in Excel, click User Guide and About Rainbow, then click Register a new licence, and enter (copy and paste) your new licence key on the registration form. Click OK and follow the prompts, and Rainbow will display confirmation of your licence details.
