When dealing with Autodesk software, particularly 2021 versions, "license patchers" are often unofficial, third-party tools used to bypass activation. If you have used one and need to remove it to restore a legitimate license or perform a clean reinstall, follow these steps to ensure all traces are gone. 1. Remove the Patcher Components
Unofficial patchers often install custom services or modified files. Identify the Source:
Most patchers (like those from "X-Force" or "MAGNiTUDE") run as standalone executables. Locate where you first ran the patcher and delete those files. Stop Services: Task Manager
(Ctrl+Shift+Esc) and look for suspicious services such as "Autodesk Desktop Licensing Service" (if it looks tampered with) or custom "LMTOOLS" instances. Check the Hosts File: Patchers often modify your Windows file to block Autodesk servers. Go to C:\Windows\System32\drivers\etc with Notepad, and remove any lines containing autodesk.com 2. Uninstall the Autodesk Licensing Service
The most effective way to "unpatch" is to remove the licensing framework entirely and let a clean installer replace it. Navigate to:
C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing Right-click uninstall.exe and select Run as Administrator
Wait for the folder to empty. This removes the core component the patcher likely targeted. 3. Use the Official Uninstall Tool
Autodesk provides a dedicated tool to handle complex removals that the standard Windows "Apps & Features" might miss. Search for "Uninstall Tool" in your Windows Start menu. Select the 2021 products you wish to remove.
This tool is specifically designed to clean up shared components and registry keys that manual uninstallation often leaves behind. 4. Remove the "Genuine Service"

If the standard "Uninstall" button is greyed out, it usually means a 2021 product is still installed. You must uninstall all Autodesk products before this service can be fully removed. 5. Clean Up Residual Data To ensure a "Top" clean state, delete these hidden folders: %localappdata%\Autodesk %appdata%\Autodesk C:\ProgramData\Autodesk (specifically the AdskLicensingService

The Autodesk License Patcher Uninstaller is a third-party script typically used to revert system modifications made by unauthorized "patching" tools. While these patchers are often used to bypass official licensing for 2021-era software like AutoCAD or Revit, the uninstaller is intended to clean up the network license manager (NLM) and background services it installs. 1. Purpose and Functionality
The primary role of the uninstaller is to "undo" the changes made by an unofficial license patcher.
Service Removal: It stops and deletes unauthorized services like the "Autodesk Desktop Licensing Service" (ADLS) or custom NLM services that the patcher might have created.
File Cleanup: It targets residual licensing files and registry keys that standard Windows uninstallation tools often miss.
Restoration: It is designed to allow a "fresh start" so a user can theoretically install a legitimate license without conflicts from previous cracks. 2. Risks of Use

Before discussing the uninstaller, we must understand the target. The "Autodesk License Patcher" refers to third-party tools (often found on GitHub or forums) that modify the adskflex.exe service, replace licpath.lic files, or patch the AdskLicensingService. These tools were designed to convert a trial version into a "licensed" version by spoofing the network license server.
While effective in 2021, these patchers are invasive. They inject code into system directories, disable firewall rules, and create scheduled tasks that auto-reset your license status.
Follow this sequence meticulously to avoid bricking your installation.
Phase 1: Preparation
Phase 2: Run the Uninstaller
Phase 3: Manual Residual Check After the tool runs, manually verify:
C:\ProgramData\Autodesk\CLM\LGS – this folder should be empty.C:\Windows\Temp for any Adsk*.log files containing the word “patch.”regedit and search for “FLEXnet” – delete any leftover keys.Phase 4: Reboot and Validate
Restart your PC. Run services.msc. Ensure no service named “Autodesk License Patcher” or fake “FLEXnet” instance is running.
