Some day OpenLiveWriter will replace Windows Live Writer (I hope)… But for now I use the Paste As Visual Studio Code plug in, and at the time of this writing, there’s nothing like that for OpenLiveWriter.
Fortunately, at the bottom of this page is a location where you can download wlsetup-all.exe: https://answers.microsoft.com/en-us/windowslive/forum/livemail-wlinstall/windows-essentials-2012-microsoft-offline/0dbbd92a-991c-48d7-8157-26decd351da8
Then, there are many posts that show this command to actually install it without having the application call out to the web for updates, which results in an error message. Here is that command (all one line):
wlsetup-all.exe /AppSelect:Writer /q /log:C:\temp\Writer.Log /noMU /noHomepage /noSearch
I finally have a location where I’m keeping this file… Those guys did this right the first time.
This was useful when I had to reinstall windows on my Surface Pro (2017)! Worked great!
