::   I can't tell about UCRT and MS Visual studio redistr. But indeed I did not
see any warning message, excepted the bug mentioned when trying to run
libreOffice.

::    Yes, you're right, the message was not exactly the same: the same phrases
but a new dll name each time. After each message, i downloaded the
corresponding dll from wikiDll.com, scanned it (with AVG antivirus) and then
put it in windows\system32, tryed to run libreOffice again to get the new dll
name and doing the same again and again ; nearly 12 times or more where
necessary to see at last LO running.
I wonder if a possible explanation is that I use Win 7 SP1 as received and
never did a single update at Microsoft.
Thank you for your detailed reply. I've changed the status to Resolved.
