Fix license manager is not functioning or is improperly installed Autocad / Revit - Windows 10/11

The license manager is not functioning or is improperly installed Autocad Revit in Win11/10/7 Fix
When launching AutoCAD or Revit on Windows 11, 10, or 7, you may encounter the error:
“The license manager is not functioning or is improperly installed” (sometimes followed by “will shut down now”). This stems from failures in the Autodesk licensing infrastructure—typically in the Autodesk Desktop Licensing Service (ADLS), FlexNet licensing, or the Autodesk Single Sign-On (AdSSO) component.

This guide provides a deep-dive, step-by-step diagnostic and remediation procedure:

Service health check & configuration

Ensure Autodesk Desktop Licensing Service is running, set to Automatic, and properly “logged on” as Local System.

If using older AutoCAD versions, verify FlexNet Licensing Service 64 is active.

If components fail to auto-register, manually re-register them via the command-line AdskLicensingInstHelper.exe using your product .pit file.

Date, time & certificate check

Ensure system clock, time zone, and certificate chain (root CA) are valid—discrepancies can block license validation.

Permission & firewall/antivirus exceptions

Grant full access and exclude these processes from antivirus or firewall:

AdskLicensingService.exe

AdskLicensingAgent.exe

AdskLicensingInstHelper.exe

Temporarily disable security software to test.

Clean uninstall & reinstall licensing stack

Uninstall ADLS via uninstall.exe, purge residual files (ProgramData, registry under HKLM\SOFTWARE\Autodesk and HKCU\SOFTWARE\Autodesk), then reinstall ADLS with “Unblock” property enabled.

Repair or reinstall AutoCAD / Revit

After restoring licensing service health, perform repair installation or full reinstall of the host application.

Before reinstall, delete residual licensing data (e.g. in C:\ProgramData\FLEXnet, %TEMP%)

Network & connectivity validation

Some errors arise if api.autodesk.com or licensing endpoints are blocked. Check DNS, firewall, VPN settings.

Edge cases & fallbacks

If multiple Autodesk versions exist (e.g. 2019, 2020, 2023), version conflicts sometimes cause licensing to break.

In extreme cases, restoration to a previous OS state or fresh Windows install may resolve deeply rooted conflicts.

By following the above escalation sequence—starting from services → component updates → permissions → clean installs → network checks—you’ll address both common and cryptic root causes of the “license manager not functioning” error on AutoCAD/Revit across Windows versions.
