The product keys for Legrand CRM 4.6 and earlier will not work with Legrand CRM 5.0.
You will need to obtain new keys.
If you're a Legrand customer and you have current Legrand CRM Software Maintenance, the upgrade to Legrand CRM 5.0 is free and your product keys will be supplied for free!
You can either obtain your Legrand CRM 5.0 product keys directly from your Legrand Partner or contact us directly for more information.
If you don't have Software Maintenance, the upgrade cost is 50% of the current license cost. You can order an upgrade from your Legrand Partner or contact Legrand Software for more information.
