Sometimes, after installing Assembly Copier, Autodesk Inventor may block the add-in and prevent it from loading.

To enable Assembly Copier:

  1. Open Autodesk Inventor.
  2. Go to Tools → Add-Ins to open the Add-In Manager.
  3. Find Assembly Copier in the list.
  4. Select the following checkboxes:
    • Load Automatically
    • Loaded/Unloaded
  5. Close the Add-In Manager.

Assembly Copier should now be enabled and available in Autodesk Inventor.
