Problem playing asf file on Win7

Dima
    Hello!

    I have Oracle Beehive 2.0.1.7.

    There is no way to reproduce the recorded online-conference (asf) file by using the standard for Win7 player (version 12.0.7601.17514).

    Installed Oracle Beehive Conferencing Codecs 2.0 from Oracle Beehive Download Center.

    1. Can anyone explain why?
    2. Is there any solution for this issue?
    3. Which player (or Codecs) should be used to play asf files under Win7 SP1?

    Happy New Year.

    Dmitry.
