If you are using the 64-bit version of HIS 2006, Biztalk Adapters for Host Systems (BAHS) 1.0, HIS 2009 or BAHS 2.0 and are planning on using Transaction Integrator (TI), you need to be aware that TI does not support COM on 64-bit systems. Only .NET is supported on 64-bit systems.

If you install TI on a 64-bit system, you will get an error message like the following when opening TI Manager if you are using a COM-based TI application:

Event ID: 5750
Description:
(5750) Transaction Integrator snap-in encountered an error in the registry  that indicates that Transaction Integrator is not configured or installed correctly:

Exception description:
(5632) The Object with GUID {GUID} is of type COM, which is not supported for an installation of Transaction Integrator on a 64 bit operating system.

If you want to stay with a 64-bit implementation, the migration path for TI is to import the old COM-based TLB (Type Library) into a new TI .NET assembly.

One thing to be aware when doing this is that the Currency data type is not supported in .NET and will be mapped to a Decimal data type. After the conversion you will need to verify that the scale, precision and host type are correct for your specific environment.
