# How can customers deactivate their license? If you would like to allow your customers to deactivate a license in order to activate it on another computer, QLM provides several solutions as described below. ### 1. Online Computer If the computer on which the license is currently activated is functional and online, a customer can deactivate a license in one of the following ways: * Using the QLM License Wizard / Deactivate option. * Using the QLM API as described [here.](/docs/how-to/how-to-clear-license-keys-from-an-end-user-system.md) ### 2. Offline Computer If the computer on which the license is currently activated is functional but offline, a customer can deactivate a license in one of the following ways: * Using the QLM License Wizard / Offline Deactivate option as described in the Offline Deactivation Code of [this article](/docs/fundamental-concepts/how-does-offline-activation-work.md). * Using a combination of the QLM API [CreateDeactivationCode](/docs/api-reference/.net-api/qlmlicense/client-side-methods/createdeactivationcode.md) with the [QLM Self Help](/docs/self-help-customer-site/how-to-configure-the-qlm-self-help-web-page.md) portal / Deactivate option. * Using the [QLM Customer Portal](/docs/qlm-customer-portal.md) ### 3. Damaged Computer If the computer on which the license is currently activated is not functional, the customer cannot generate a deactivation verification code and use the QLM Self Help Portal to deactivate his license. Your options are: * Remove the requirement for a deactivation verification code by setting the [Server Property](/docs/qlm-license-server/server-properties.md) showDeactivationVerificationCode to false. This will allow the user to deactivate the license from the QLM Self Help portal even if the computer is no longer functional. * Perform the deactivation on behalf of the customer from the QLM Management Console. QLM also provides a mechanism for preventing users from cheating by claiming that their computer is dead. This mechanism is only effective when the "dead" computer goes back online.
