problem with compilation

Dear all,
I installed MiTex 2.9 on my new computer, and now a can't produce any
document which includes a bibliography. I still succeed to work on my old
computer, so I guess the problem is not in latex files themselves, but
something perhaps something in installation/compatabilty to windos doesn't
work. The error notificaion I get is

I couldn't open style file harvard.bst

---line 62 of file myfile.aux

: \bibstyle{harvard

: }

I'm skipping whatever remains of this command

I found no style file---while reading file myfile.aux

(There were 2 error messages)


Sorry, but "C:\Program Files\MiKTeX 2.9\miktex\bin\x64\texify.exe" did not
succeed.

Thank you for any assistance.
Artyom
