Windows Live Writer was an excellent Blog Publishing Tool. Unfortunately, it was discontinued and has not been available since 2017.
I then started to use Open Live Writer which was a free open-source fork of Windows Live Writer.
But the last time I used it, it would not publish to my WordPress blog. After spending a few minutes playing around with it, I decided to uninstall and re-install. But it was no longer in the App store. I am certain I would have downloaded it from the MS store.
But it appears that you have download the installer from the website.
This the web site https://openlivewriter.com/
I downloaded the installer and attempted to run it. However, when I got to the part where you input the log in details for the blog, it came up with the same message as before – it could not locate the blog. I had disabled the relative plugin preventing this.
So, it looks like I can no longer use this app and I will have to go back to using the new post tool on WordPress.
