My connection Partner is running an old version and there is no one in front of it?

I have tried to install all the old versions on my windows(11,12,13 and 14) and I could not connect to my connection partner that shows a message "you are running an old version which is out of date".

I know that I need to check for a new version for my partner and upadte the current version but there is no one in front the computer there.

Is there any other solution here?

Thank you.
