# Deactivate License Page

### QlmReleaseLicense.aspx <a href="#h_01hdm5wzxv8q8mxzw1y5w2xffp" id="h_01hdm5wzxv8q8mxzw1y5w2xffp"></a>

**QlmReleaseLicense.aspx** is a web page that your users can fill out to deactivate a license from a given computer. You can launch this page with or without any arguments. If you provide arguments, the corresponding fields in the form will auto-populate with the provided values.

If you enable the [Server Property](https://support.soraco.co/hc/en-us/articles/207920563-Server-Properties) showDeactivationVerificationCode, a customer will need to enter a Deactivation Verification Code (DVC) to deactivate a license. If you are using the QLM License Wizard, the wizard will display the DVC when an offline user tries to deactivate a license. You can also use [CreateDeactivationCode](https://support.soraco.co/hc/en-us/articles/360031442411-QlmLicense-CreateDeactivationCode) API to create a DVC.
