The following error message is displayed when you launch your subscription product. You are using the correct serial number when installing your subscription product.

Causes:
This error typically happens if you don’t auto-renew your license. When you re-subscribe to a new subscription, you will get a new serial number. In your account, you will have the older invalid serial number [556-xxxxxxxx] visible for 30 days past the expiry date and the new valid serial number [551-xxxxxxxx] listed in your account.
Solution:
- Confirm on your Autodesk Account that you have old and new serial number listed in your account. If the old serial number is not visible the previous subscription expired more than 30 days in the past.
- Install the software using new serial number [i.e. 551-xxxxxxxx] and product key.
- When dialog box window comes up, put in old serial number [i.e. 556-xxxxxxxx].
- Let the product run.
- In About Product dialog box, confirm that new serial number is listed.
NOTES:
If your serial number
is correct and you still receive the “Renew your license” error, you would need to reset your local license information:
- Rename/remove the following folders and re-start the product:
Windows:
- Close any running Autodesk programs [make sure Autodesk Desktop App and A360 are also shut down completely from the taskbar].
- Remove all files under C:\Users\\AppData\Roaming\Autodesk\ADUT
- Remove all files under C:\ProgramData\Autodesk\ADUT
- Go to C:\ProgramData\FLEXnet and delete all files that start with adskflex
- Go to C:\Users\\AppData\Local\Autodesk\Web Services and delete the file LoginState.xml
Mac OS:
- Close any running Autodesk programs.
- Turn off Time Machine if it is running.
- Remove all files under /User//Library/Application Support/Autodesk/ADUT
- Go to ~/Library/Application Support/Autodesk/Web Services and delete the file LoginState.xml
- Navigate to /Library/Preferences/ and locate the FLEXnet Publisher folder.
- From within the FLEXnet Publisher folder, delete all files that start with adsk.
Note: Other products might use this licensing technology. Adobe may have some files in this location as well. Do not remove any non-Autodesk files.
Note: In some cases, after these steps, you may be shown the error ” Contact your administrator to request permission to use this product“. Usually you just need to assign permissions to the users in your Autodesk Account.
- Go to C:\ProgramData\Autodesk\Adlm and delete the file of the correspondent product:
- Check the LAN settings and Internet options to make sure they match the settings in the link
- If you reset your local license information and still get the error message, this is an indication that the PIT file has been corrupted. You will need to perform a clean uninstall\reinstall of all Autodesk Products. This will allow you to create a new pit file:
