probelmes with windows installer (complete)

[Erwin Auer]

When the installing is almost complete the installer cannot find the 
file lyxrc.defaults. Later on when starting LyX the program states 
"cannot find lyxrc.defaults"
I used the LyX141 installer from 
ftp://ftp.lyx.org/pub/lyx/contrib/LyXWinInstaller

Can you please help me.
best regard
Erwin
