Abstract:
- No extra cost for 64-Bit support
- Assign the orchestration to run in a host instance that has the 32-bit only property not selected. The host instance must be running on a Windows x64 machine.
- BTS 2006 requires CPU hardware that supports AMD64 or EM64T but does not support Itanium-based hardware. However, BTS 2006 does support running with an Itanium-based SQL Server 2000 or SQL Server 2005 deployment
- BTS 2006 allows to create MSI file that can contain both 32-bit and 64-bit dlls and exes that were added to the BizTalk application. On 32-bit Windows, only the 32-bit dlls and exes will be installed. On Windows x64, both 32-bit and 64-bit dlls and exes will be installed
