How to do a manual clean uninstall of Autodesk Fusion.
 

WARNING: The Fusion Service Utility (FSU) provides a safer, lower effort alternative to the following manual process. Manual clean uninstall process is high effort and only necessary in extreme cases.

If you are reinstalling, use the Repair Fusion (FSU command)
If you are uninstalling, use the Uninstall Fusion (FSU command).
 

Before Uninstalling, back up any local Libraries with one of the following methods:

  • Load the local library into a Cloud library: 
  • Change the file name of the existing folder instead of deleting it:
    1. Locate the local library or other files that need to be kept through the Manual Clean steps.
    2. Add something to the file name such "old" or "keep". For example change "CAM360" to "CAM360_old" or "CAM360_keep".
    3. Do not delete that file.
    4. Reinstall Fusion.
    5. Fusion will have created a version of the folder and the name changed folder will also still be there. 
    6. Restore the folder with one of the following methods:
    • Delete the newly created folder and change the old folder back to the standard name.
    • The internal contents of the renamed folder can be moved to the newly created folder. 
  • Drag or copy files to be kept to a new location:
    1. Locate the local library or other files that need to be kept through the Manual Clean steps.
    2. Drag or copy files to be kept to a new location, such as to the desktop so they are not deleted or overwritten during the reinstall.
