How to get cis_setup_x64.msi to install off line

When you run the online installer - it downloads the cis_setup_x64.msi 131MB file.
That file cannot be run off line, but the online installer does work if you just let it go through and finish.

Was this done on purpose to make it impossible for users to have an offline installer of latest v12.2.2.7036?

Haven’t been on here for a long time - is it possible to get an offline installer, are there workarounds to make that .msi file work offline?
