Profiling 64bit ASP.NET 2.0 App W3SVC-WP Error

Is it possible to profile 64bit apps with Ants Profiler?

I get the following Event Log Error:

ISAPI Filter 'C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_filter.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture. The data field contains the error number.

    No -- ANTS Profiler can only profile 32-bit code. If it encounters 64-bit code, we're not sure what possible consequences there could be. You may be able to profile 32-bit code on x64 systems. As far as I know, it's just the core component, which is COM-based, that will have problems with 64-bit pointers, etc.

    We will be looking at 64-bit support in the near future. Thanks!
