If you’re seeing errors like:
- ❌ “No license found. Please connect to the internet or check your license server.”
- ⏳ “License checkout timed out.”
- ⚠️ “You are not licensed to use this product.”
Don’t worry — these are common Autodesk licensing errors that can be fixed with a few simple steps.
This guide works for: ✅ AutoCAD
✅ Revit
✅ Civil 3D
✅ 3ds Max
✅ Inventor
✅ Maya
…and other Autodesk software.
🔍 Why This Happens
These errors usually occur due to:
- No internet connection or unstable Wi-Fi
- Autodesk Desktop Licensing service not running
- Corrupt license cache
- Firewall or antivirus blocking access
- Old or expired license files
🛠 Step-by-Step Fix
✅ 1. Restart Autodesk Licensing Services
- Press
Win + R
, type: CopyEditservices.msc
- Look for:
- Autodesk Desktop Licensing Service
- FlexNet Licensing Service
- Right-click → Restart both services
🔄 Then restart your PC and try launching AutoCAD or Revit again.
🧹 2. Delete Licensing Cache
- Open this folder: makefileCopyEdit
C:\ProgramData\Autodesk\AdskLicensingService
- Delete the entire folder named “AdskLicensingService” or any temp/cache files inside it.
- Now go to: makefileCopyEdit
C:\Users\<YourUsername>\AppData\Local\Autodesk\Web Services\
- Delete any files named
LoginState.xml
💡 This resets corrupt license files and login issues.
🌐 3. Check Your Internet Connection
Make sure:
- You are connected to a stable internet
- No VPN or proxy is active
- Try restarting your Wi-Fi or switching networks
🔥 4. Disable Firewall/Antivirus Temporarily
Sometimes your firewall or antivirus blocks Autodesk license checks.
✅ Try turning it off temporarily:
- Windows Defender → turn off real-time protection
- Third-party antivirus → turn off or add Autodesk folder to exceptions
Then restart Autodesk software and see if it works.
🌍 5. Log In to Your Autodesk Account
- Go to https://manage.autodesk.com
- Log in with your Autodesk ID
- Ensure your product license is active or assigned to you
Then open the software again — it should recognize your license.
🔄 6. Reinstall Autodesk Licensing Service
If none of the above work:
- Download the Autodesk Licensing Service Installer from the official Autodesk support page:
🔗 Official Link
- Run the installer
- Restart your PC
Then relaunch your Autodesk product.
🧠 Bonus Tip: Use AutoCAD in Offline Mode
Once activated, you can use Autodesk software offline for up to 30 days. But make sure to log in once a month to renew.
