Software Maintenance


MOSEK is constantly improving and new features are added regularly. For instance, MOSEK is tuned for the latest hardware and operating systems. If you plan to use a MOSEK license for an extended time period and always want the latest version, we recommend that you purchase maintenance for your licenses. It carries the following benefits:

  • Free upgrades of the license through major versions, i.e. you can upgrade for free from version 9 to version 10 and so forth. We expect to release a new major version about every second year.
  • Prompt response to bug reports.
  • Highest priority when requiring enhancement for the solver.
  • Free hostid changes for the license.
  • Email and phone support.


  • The maintenance period covered is always explicitly stated on quotes and invoices using the corresponding Part IDs with suffix -MAIN. Look for 'start date' and 'end date' in the maintenance section.
  • If maintenance is not mentioned on a quote or an invoice, then the purchase does not include any maintenance.
  • Maintenance expires at the end of the year.
  • At least one month before the maintenance expires we will mail a renewal quote for the following year to the license owner.
  • Maintenance is cheaper when paid in advance. If you choose not to renew but change your mind at a later date, then the cost will be higher.
  • A license must be under maintenance from the day of purchase until the maintenance expiration date. There cannot be holes in the maintenance period.
  • For licenses without maintenance only one hostid change is allowed.
