In my case I wanted to write an urgent letter with LyX but could not use it and had to use LibreOffice instead. regards Uwe I'm on windows 7 and MiKTeX 2.9. MiKTeX update failed about a week ago and I couldn't compile to pdf, nor did instant preview work. The following day I tried updating again, and everything worked as it should, and as it has done since (including 11 packages updated just a few minutes ago). MiKTeX updates from ftp://ftp.tu-chemnitz.de which seems a bit odd for someone in New Zealand but MiKTeX selected this itself with no help from me. (I think using the "random package on the internet" option in the console.) I've now also, after the update, compiled a complicated master-child document to pdf, so everything is working as it ought.

The fix for MiKTeX was already released but the main update server of MiKTeX is down. One cannot retrieve any update yet, no matter what update server is chosen. regards Uwe
Re: WARNING: updating LaTeX or LyX under Windows will currently break LaTeX installation
> I had this problem trying to install MikTeX and LateX on a new Windows computer. I got that message about an unknown procedure entry point. After uninstalling and re-installing several times, I got MikTex to work. Lyx still tells me there is no PDF viewer installed, as I described in another thread.Hi Rick, yes the problem you having is exactly the one I described. So currently there is no workaround than to wait until MiKTeX is fixed.Regards Uwe
WARNING: updating LaTeX or LyX under Windows will currently break LaTeX installation
Dear LyX Windows users, yesterday I noticed a severe bug in the LaTeX system "MiKTeX" that LyX is usually using under Windows. The problem is that if you - upgrade MiKTeX or LyX or - install a new LaTeX package or - refresh the MiKTeX package database you will end up in a broken LaTeX with error messages like "unknown procedure entry point". I experimented around for more than 2 hours but could not find a workaround once LaTeX is broken. Even a reinstallation of LyX or MiKTeX doesn't help since the result are always broken DLLs and I could not find a way to prevent this. Therefore I strongly recommend not to change anything in your LaTeX setup nor to compile LyX documents that might use special LaTeX packages hat are not yet installed on your PC. Also don't install another version of LyX or reinstall LyX. I hope this issue will be fixed soon and report back. regards Uwe
