windows version of lyx1.4.3 not working

[Ruijs, Arjan]

Hi,
 
I just tried to install the windows version of LyX1.4.3 but it doesn't do 
anything. When I run it from the command line it gives the following message:
LyXTextClassList::Read: unable to find textclass file ''. exiting.
 
When I run the -dbg 66535, it says that something with the path needs to be 
corrected as apparently in the fonts directory he uses a / instead of a\ (or 
something like that).
 
Does anybody know what's going wrong and what I can do about it.
 
Regards,
Arjan
