converting access from 32 bit to 64 bit Access 365

Looks like you are trying to import from the MDE again. You can't. See my answer in post #20



The system tables are hidden by default.
They only become visible if you tick Show System objects in Access navigation options.
Don't try & edit or delete them or your database may become permanently ruined
Some of the system tables are 'deep hidden' which means you still won't see all of them in the navigation pane

If you look in the relationships window, the system table links may be shown there (this is from an ACCDB file)

agree with colin - the list of forms is not the same per your first post

MSSysNavpaneGroupCategories is a hidden table and AGAIN was never in Access 2000. You need to remove the replication in Access 2000 or even Access 2003.
