I thought I’d create a blog post after a long time away and fired up Live Writer. It instantly crashed every time with a Live Writer has stopped working error.
Tried the usual; reboot, repair, uninstall, reinstall. No success. Searched the Internet and found useful articles here and here and here and here, but still no success. Searched Event Viewer and couldn’t find the issue.
Finally, I came across this article. It turns out that if you have your documents folder on an external drive (I have an internal SSD and a much bigger external disk), and Live Writer can't see this folder, then it will crash at startup. Reattached my drive and all is good.
