OO 24.1.2 and 24.1.1 are released as patches, so standalone installers for those versions are not provided. If you are considering using these versions for the first time, please install the older versions before upgrading to these versions.
Note that both versions can be directly upgraded from OO 2019.07 or later. Upgrading from versions from 10.0x to 2018.12 requires a step upgrade.
