Identifying License Errors in AutoCAD 2018
License errors in AutoCAD can manifest in different forms, including warnings about invalid or expired licenses. These issues may hinder your ability to use the software effectively, prompting the need for corrective measures.
Procedure to Fix License Errors in AutoCAD 2018
Follow these detailed steps to resolve license errors in AutoCAD 2018:
Step 1: Terminate AutoCAD Processes
Begin by opening the Windows Task Manager. Look for any running instances of AutoCAD and end these tasks. This ensures that the software is completely closed, allowing you to make necessary changes without interference.
Step 2: Deleting Autodesk Licensing Files
Next, navigate to a series of folders on your computer that contain licensing information:
- Open File Explorer and input C:\Users\
\AppData\Roaming\Autodesk\ADUT in the address bar. Delete all files found within this directory. - Then, go to C:\ProgramData\Autodesk\ADUT and remove all contents from this folder as well.
- Proceed to C:\ProgramData\Autodesk\CLM, and delete the folder labeled “LGS.”
- Lastly, visit C:\ProgramData\FLEXnet and delete all files starting with adskflex.
Step 3: Reboot Your Computer
Rebooting your computer is crucial after deleting licensing files, as it refreshes the system and prepares it for the next steps in the activation process.
Step 4: Reactivate AutoCAD
Once your system has restarted, relaunch AutoCAD. You might encounter an activation dialog. Choose to either “Try” or “Activate” the software. Follow the on-screen instructions to proceed with the activation process. You may be required to enter your serial number and product key during this stage.
Step 5: Verify Activation
To confirm that the software has been successfully activated, access the Help menu, and click on “About AutoCAD.” In the ensuing window, look for Product Information to view your license status, including any applicable serial number and license type.
Common Questions About AutoCAD Licensing
How can I check my AutoCAD license type?
To determine your license type, launch AutoCAD and navigate to the Help menu. Select “About,” then look for the “Product Information” section where your license details will be displayed.
What should I do if I’ve lost my AutoCAD activation serial number?
If you lose your serial number, check your Autodesk account under the products and services section, or consult any purchase receipts. If these aren’t available, contacting Autodesk customer support may help retrieve your serial number.
Can I use AutoCAD on multiple devices with a single license?
The ability to use AutoCAD on multiple devices with a single license depends on the license type you purchased. For instance, a network license allows usage on multiple machines, while a single-user license is generally restricted to one device unless specified differently in your purchase agreement.
