    That looks like OO4O code. I hate to be the bearer of bad news, but it's one of two likely problems:

    1. If you installed the 64 bit Oracle client, OO4O isn't in it. OO4O is discontinued and not supported in 64 bit.
    2. If you installed the 32 bit client in a 64 bit OS, I've seen cases where the registry entries to register OO4O aren't properly created. If you manually register everything it will usually work, but it's still not supported in a 64 bit OS.

    If it's all 64 bit, you don't. OO4O isn't in the 64 bit driver.
