missing ugrade files

Hi

We have MYOB accountants office version 2021.0 version 5.4.37.96 and want to upgrade to the latest. But in order to ugrade to version 5.4.41 it says we need version  5.4.38.100 but there is no download for .100. Even the instructions to download the version 5.4.38.101 says we still need 5.4.38.100 first. Where do I get 5.4.38.100 from because its not on the download list.
