A few days ago I installed the newly released beta 2 of Windows Live Writer, and immediately noted (with a bit of disappointment) that the spell checker was missing... After various tests (reinstalling on other machines I have, checking that all assembly versions were the right ones etc...) I decided to open a call through http://support.live.com (yes, this time I've been the customer and not the Support Engineer ).
They've been very quick, and after a few emails I've been pointed to this post: the trick is use this custom launcher instead of running WindowsLiveWriter.exe directly, and I got my spell checker back and working like a charm .
Following up this with the WLW support and we found that, even if I'm running only English operating systems (WinXP, Win2003 and Vista x64), all with Italian keyboard layout, and at least on the XP machine I also have the Italian .NET Framework package, the difference is made by my Regional and Language options which, as you may guess, I set to Italian; as a test I switched it to English US and the spell checker showed up in the Tools menu even without the custom launcher. It worth mentioning that the spell checker is currently only available for English language, but the Writer Product Team is working to add more language in the future. And of course the PD is aware of this problem, and hopefully they'll fix it in the next release.
