How to Reset License Activation for an Autodesk Product for Stand-alone License with Single-user Access

Understanding the Activation Reset Process for Autodesk Products

Many Autodesk software users may occasionally confront issues requiring them to reset their software activation. This guide provides detailed instructions for resetting the activation of a stand-alone Autodesk product licensed for single-user access.

Common Scenarios for Resetting Activation

Resetting your software activation may be necessary in the following situations:

• The software fails to launch.
• Activation is unsuccessful despite following the prompts.
• Frequent error messages, such as Error 0015.111 or Error 0015.301, manifest during the activation process.

Causes of Activation Issues

Subscription licenses typically require regular renewal intervals—monthly or quarterly. If your software was purchased after August 1, 2016, it likely utilizes a subscription model. In the event of an activation error, it may be necessary to restart the licensing process. Common messages indicating this need include:

• “Renew your License”
• “Your Trial has expired”
• “Contact your Administrator”

Preliminary Steps for License Reset

Before proceeding with the reset:

1. Close All Autodesk Applications: Ensure no Autodesk software is currently running to avoid conflicts during the reset process.
2. Visibility of Hidden Files:
   • For Windows: Enable visibility of hidden files and folders.
   • For macOS: Make hidden files visible within the Finder.
