I am attempting to upgrade from Ledger version 8.0A (040223) to version 8.0B (041005) but when I attempt to perform the install I receive the error message "this version is too old to update...". I know I must be missing a necessary update step or version but can't find the required information anywhere. Can you tell me what I should be updating with before attempting to install 8.0B (041005)?

Thanks,
-Phil
