1) I am using LyX 1.5.3 having upgraded successfully from LyX 1.5.1 some time
ago.
2) I have now just updated from MiKTEX 2.5 to MiKTEX 2.7
3) I noticed that the LyX Preferences Path prefix: was
C:\Program Files\LyX151\bin;C:\Program Files\LyX151\python;C:\Program
Files\MiKTeX 2.5\miktex\bin;C:\Program Files\gs\gs8.53\bin;C:\Program
Files\ImageMagick-6.3.2-Q16
i.e. it refered to LyX 1.5.1 and MiKTEX 2.5 directories.
I assumed this was wrong and changed the LyX paths to reflect the new LyX and
MiKTEX directories, i.e. to
C:\Program Files\LyX153\bin;C:\Program Files\LyX153\python;C:\Program
Files\MiKTeX 2.7\miktex\bin;C:\Program Files\gs\gs8.53\bin;C:\Program
Files\ImageMagick-6.3.2-Q16
4) On loading an existing document into LyX I get the following eror message
"The layout file requested by this document, article.layout, is not
usable."
I get the same error message when starting a new document
Any help to resolve this problem will be gratefully received
Regards, Graham
