Expired certificate stops from downolading installation file

I tried to download the .msi file to install the latest update to the eM Client, but when i clicked on the download button, the following message appeared:

Is it possible to fix or bypass?

Thanks in advance for your support.

Can you try a different web browser please.

Hi Gary and thanks for your reply.
I tried with another browser (many actually) on same computer and also antivirus blocked access with the message shown below.

On another computer just having MS Defender, the download succeeded.

It just resumed to work also on 1st computer: did you make any change?
