download older version of icloud

I have Windows 11 and the Microsoft office apps from Office365 subscription .

The latest version of Icloud (14.2) does not work.

I am told by Apple support that a workaround is to install an older version of Icloud.

Where can I locate an older version please. Other users have told me 7.2.1 works OK

So how do I get an older version???

Microsoft store only has the latest vsersion.

thanks
