Then you are on Windows Vista, right? For an unknown reason the program
that handles PDFs when they are open fails on Vista. I will provide a
workaround, but me was told I first should wait if the Vista Service
Pack 1 fixes this. Have you installed the Service Pack 1 for Vista that
is available since 2 weeks at microsoft.com? If not, does it work when
you install it?
If nothing helps, reinstall LyX 1.5.4 using the official installer that
uses a different method to update PDFs. But now you have a working and
full featured LaTeX installation and the third-party programs like
Ghostscript are up to date.
What is the reason to use this alternative PDF viewing method? I think
we should use the same application for both installers.
