Office Pro 2024 LTSC offline deployment fails on Windows 11 24H2

So I downloaded the necessary files, and transferred to an offline computer. Trying to install using Admin command (setup /configure OfficeVisio2024LTSCConfigRem365.xml) gave a couple of errors (error codes 30182-44 (2) and 0-2031 (17004)). Then, to test, the computer was onlined and it started to work, with max bandwidth used.
From this, it appears the setup.exe could not find/access the downloaded files, in which case it defaults to online installation.

But why, the folder structure is
‘C:UsersxxxxDesktopOffice 2024 ltscOfficeData16.0.17932.20602’
and the setup and config files are placed in the ‘Office 2024 ltsc’ directory.

The config file used is shown below:
