LyX ⇒ Can't export Hebrew LYX file to PDF

[benavon]

I installed LYX by the official instructions.
When I view[ctrl+R] a document which includes only English text - a new PDF file open properly, but if the document includes Hebrew letters I get an error (attached as picture). I had tried to download 'culmus.sty' file and copy to some directories, but it didn't help.
~ The files directories which were mentioned:
[*] AppData\Local\Programs\MiKTeX\tex\latex\culmus
[*] AppData\Local\Programs\MiKTeX\tex\latex\tools
[*] AppData\Roaming\MiKTeX\2.9\tex\latex\culmus
[*] C:\Users~myUserName~\culmus\tex\latex\culmus
Thanks
error output
