This hasn't got anything todo with the registry (much). Accounts, passwords and stuff are mainly saved and handled by the Windows User Credentials. Tweaking the registry will not help...
CACLS is used to change the rights of other people towards the account your using this command with. Not vice versa as that would of course be a huge security hole.
PS: CMD is the DOS command prompt. It isn't a "program" per se.

The directory name can be different, that doesn't matter. The important thing is that the credentials are the same as the old one (aka, the username and password)...
But as I can read from your post, you should not make a user named "Ollie", but "Olixander", as that was the last working username for that corrupted directory, so try that.
