Minor revision updates and bug fixes are included with annual maintenance. Major version updates (e.g., moving from LC6 to LC7, or from LC7 to LC8) require the purchase of a new license.LC7 customers who are current on their annual maintenance will be elegible to purchase LC8 at a discounted rate. Microsoft has a history of making changes at the OS level which break security tool functionality. If this happens, we will update LC to add compatibility when possible.


Your LC7 license includes 1 year of support and updates. To continue to receive support and updates after the initial 1-year period, you must pay an annual maintenance fee.
