Find request code for manual activation

Autodesk Support

Jan 29, 2023


Note: Autodesk no longer supports offline activation for 2021 products and later. If you have a perpetual license, you can activate your software by going online only once. After you activate online, you can continue to use 2021 software and later offline. This change doesn't apply to subscription network licenses or previous versions that you already activated offline. You can continue to use them as before.

Request codes are necessary only if you have perpetual license software and need an activation code to manually activate software on a computer with no Internet access. Generating a request code is the first step in the process of manually activating your Autodesk software.

Note: Request codes and manual activation are required only for perpetual license software. You need a valid serial number and product key to generate a request code for your perpetual license software. You don't need a request code for subscription software or to access your software online using a serial number and product key.

 

To generate a request code with the product activation wizard

You see the screens for generating a request code in the product activation wizard only if your computer isn't connected to the Internet. If your computer has an active Internet connection, the software will assume you want to activate online, and it won't display the screens for a request code.

  1. Disable your Internet connection and start your software.

    This is an offline process. The following screens appear only if your computer isn't connected to the Internet.
  2. Click Activate on the Free Trial screen.

    Note: Autodesk software products operate on a free trial license until you activate them. If you purchased your software and didn't use it as a free trial, you still need to activate your software from the Free Trial screen. Your screen may look different depending on your product, but the process should be similar for all supported products.


     
  3. Enter your serial number and product key and click Next.

  4. Select "Request an activation code using an offline method" and click Next.

    Note: You see this screen and option only if your computer has no active Internet connection. If your computer is connected to the Internet, the software will assume you want to activate automatically over the Internet, and you don't see the screen for generating a request code.


     
  5. For future reference, keep a record of the activation information provided.
  6. Activate in one of the following ways:
    • Enter the information at register.autodesk.com to get an activation code instantly.
    • Complete the web request form using the link on the screen. (This request may take up to 48 hours.)
  7. Click Close to exit the wizard and resume using your software in trial mode.

 

Finding stored registration information

Most products generate an HTML file with your request code and registration information when you install your Autodesk product using a valid serial number and product key.

Note: The registration file described below may not be available for all products and platforms. If you can't find a previously generated request code, generate a new one following the previous instructions.

To find a request code saved on your computer

  1. Search for USRegInfo.html on your computer.

    Note: The file's location and name vary according to your product and operating system. Here are examples of typical locations for the registration information:
    • For Windows:
      C:\ProgramData\Autodesk\Adlm\ ProductNameVersion_USRegInfo.html
    • For macOS:
      /Library/Application Support/Autodesk/Adlm/ProductNameVersion_USRegInfo.html
  2. Open the file with your product name and version in the file name.
