I’ve used Windows Live Writer in the past, and it has been a little flaky. I’m happy to say that their latest beta (its been out for a few months now) is a lot better. Much faster, and is working well handling images (something I had trouble with in the past version).
Note: If installing on Vista you’ll most likely have to Run as Administrator to install. By this I mean you need to right click on the Installer and click ‘Run as Administrator’. This is a little weird because all my other applications have simply used a UAC popup to gain necessary permissions when installing.
If you don’t Run as Administrator, the installer will run, prompt via UAC, ask you to agree to T&Cs, ask if you want MSN as your search page, start installing but then hang.
