4. Enter "ACDSee" in the Find dialog box and delete all relevant content found; (Note that it is best to use "file-and-export" to back up the registry before deleting it, and then find it again to confirm that it has been removed)

3, close the Registry Editor, with "Super rabbit" and then clean up the registry and hard disk (all ACDSee related installation files, including hidden, deleted)

I wish you a smooth solution to the problem:)
