For example, you are having Windows 32 bit (this Windows is not supported by MT5 anymore), or you downloaded MT5 from the broker's website instead, or for any other reason.
You can install fresh MT5 (use the link at the bottom of this page) and install MT5 on your Windows 10 64 bit, after that - connect your MT5 to MetaQuotes-Demo server and update.

If you have a question, first of all you should show the first three lines from the 'Journal' tab

You seem to be using a 3rd party VPS. Please be aware that many VPS providers block certain Internet protocols, ports and addresses. That may be the reason for the failure to download the update.
Off-topic but very important! You should not be actively using the Administrator account on a VPS. Doing that is a very high security risk. You should configure a separate account for general usage and only use the Administrator account for critical access.
