    Are you trying to run the worker process as Wow64(32-bit)?

    In that case there is a good chance that your configuration is trying to load some 64-bit isapi filter, for example aspnet_filter.dll,for v2.0, on a 64-bit OS there will be two instances of this dll on your machine under \framework and \framework64 folders. You want to select the one under \framework.

    Thanks,
