If you intend to run 32-bit ASP.NET applications on 64-bit Windows, you must configure IIS to create 32-bit worker processes. For more information about running 32-bit applications on 64-bit Windows, see Running 32-bit Applications on 64-bit Windows.
IIS cannot run 32-bit and 64-bit applications concurrently on the same server.
