Registry Cleaner, structured list permissions fix creates no backup . . . . . . . . . Unknown. . . . . . . . . . . . . (1)
Then, in a separate run, I deleted the "does not exist" item. A backup was created, and the message box had correct numbers.
After restoring the backup, I used the Fix button for the item. A backup was created. However, the message box message appeared to have the header line in the entries count (it said 2 but there was only 1).
