Hi All,

Are there seperate installation files for 32 bit and 64 bit of BizTalk 2006
or while installing, BizTalk will determine which one to install based on OS.
Can anybody clarify this.

Thanks.

Chris,
Its a while since I did a 64-bit install of BizTalk, but I seem to
remember that the install CD includes both versions and that it
figures out the correct install depending on the target system (but I
could be wrong on that, I'd be happy for that statement to be
clarified).

A few points to take away:

* BizTalk supports both 32- and 64-bit architectures out of the
box.; Itanium (ia64) is not supported, but x64 (AMD64 and EM64T)
architectures are. This applies to the BizTalk runtime only and not
the SQL Server database - you can run SQL Server on any supported
hardware.

* The BizTalk runtime can execute in 32-bit mode using the WOW64
service to emulate a 32-bit runtime environment. On an x64
architecture, WOW64 switches the processor hardware from its 64-bit
mode to compatibility mode when it’s time to execute a 32-bit thread,
and then handles the switch back to 64-bit mode. No expensive
emulation is required for WOW64 on x64 in comparision to Itanium. For
more information, see the Wikipedia entry on WOW64.

* Installation is relatively simple and requires no additional
work. If you are downloading the CAB file prior to installation
(rather than letting the installer download from the web), make sure
that you get the 64-bit version, rather than the 32-bit version.

* On a 64-bit architecture, Setup installs the 32-bit elements
into the ‘Program Files (x86)’ directory, rather than the standard
‘Program Files’ directory.

When developing projects, I would suggest targeting your assemblies to
GAC_MSIL, rather than GAC_32 (32-bit) or GAC_64 (64-bit); that way,
the JIT compiler can target your assembly to the correct version of
the CLR at runtime and you don't have to worry about compiling to the
correct architecture when developing.

I blogged on the topic of 64-bit BizTalk sometime last year:

Be aware though, there are a few caveats with 64-bit BizTalk, e.g. the
BizTalk Explorer OM doesn't work:

Hope this helps, Nick.
