Why do you recommend the 32 bit version even when the OS is 64 bit Windows?
The main reason is app compatibility, which is why 32-bit Office 2010 is recommended even on 64-bit Windows. There are very few if any 64-bit add-ins for Office. For a more thorough discussion on the difference between 32-bit and 64-bit Office, please take a look at these docs:

Thursday, November 19, 2009 4:00 AMHi dgh725--
I'm not aware MSFT or anyone else makes this recommendation--or at least in reading a lot of 2010 documentation, I haven't seen it. If you have a duo or multicore box, which would include any notebook or laptop from the past 3-4 years, I'd install 64 bit Office, and 64 bit Windows.
You can take advantage of the architecture of a multicore processor.
If there is any recommendation to install 32 bit Office, on 64 bit Windows, I'm missing something. I have not set up benchmarks on multiple machines for a lab comparison, but you will be fine installing the 64 bit choice on your 64 bit Windows which by definition wouldn't have installed on a box that couldn't accomodate both of them.
Good luck,

Thursday, November 26, 2009 12:48 AMSome users report that the Office beta, and some other x64 apps too, are slower on PCs <4 GB.

Tuesday, December 01, 2009 12:38 PMAh! So it doesn't really matter that I couldn't find the 64 bit beta download by the looks of it. I was running the 64 bit tech preview, but despite ages of searching, 64 bit beta Office 2010 just didn't seem to be an option so I got the 32 bit.

Thursday, December 03, 2009 3:52 PMHope this helps.Here is an article that explains it:There is a 64bit version but you have to do it differently. Here is the link for it: http://www.microsoft.com/downloads/details.aspx?FamilyID=600c2142-abc3-4fea-9271-0c326c45dc8f&displaylang=en
This link is for the article below: http://technet.microsoft.com/en-us/library/ee681792(office.14).aspxArticle:64-bit editions of Office 201064-bit editions of Office 2010Updated: 2009-11-12
[This article is pre-release documentation and is subject to change in future releases.]
Processors that are 64-bit are becoming the standard for systems that range from servers to desktop computers. The 64-bit systems can use more virtual and physical memory than 32-bit systems. This lets users work with much larger data sets than they could previously, and to analyze and solve large computational problems. Microsoft Office 2010 introduces native 64-bit versions of Microsoft Office products to take advantage of this larger capacity. For example, this additional capacity is needed only by those Microsoft Excel users who require Excel spreadsheets that are larger than 2 gigabytes (GB). The 32-bit version of Office 2010 provides the same functionality and is also compatible with 32-bit add-ins. Therefore, the 32-bit version of Office 2010 is installed by default.
Office 2010 also provides support for 32-bit Office 2010 applications that run on 64-bit Windows operating systems by using Windows-32-on-Windows-64 (WOW64). WOW64 is the x86 emulator that enables 32-bit Windows-based applications to run seamlessly on 64-bit Windows systems. Office 2010 lets users continue to use existing Microsoft ActiveX Controls, Component Object Model (COM) add-ins, and Visual Basic for Applications (VBA), which are primarily 32-bit because no 64-bit versions are available yet for many add-ins. Supporting 32-bit Office 2010 applications that run on 64-bit operating systems allows for better compatibility with controls, add-ins, and VBA.
This article applies to the current release of Office 2010. For a visual representation of this information, see 64-bit Client Installation of Microsoft Office 2010(http://go.microsoft.com/fwlink/?LinkId=168620), which includes supported scenarios, deployment considerations, and an overview of the Setup process.

Supported Windows operating systems
The supported Windows operating system editions for 64-bit Office 2010 client include the following:
- 64-bit editions of Windows Vista with SP1
- 64-bit editions of Windows Server 2008 with Service Pack 1
- Windows 7
- Windows Server 2008 R2
The following statements apply:
- The 64-bit Office client can be installed only on 64-bit editions of Windows Vista with SP1, 64-bit editions of Windows Server 2008 with Service Pack 1, Windows 7, and Windows Server 2008 R2.
- The 32-bit Office client is supported as a WOW64 installation. This is the default installation on 64-bit Windows operating systems. The 32-bit Windows-based applications run on 64-bit Windows, which allows for compatibility with 32-bit Office applications and add-ins.
- Office 2010 server products (Microsoft SharePoint Server 2010, Microsoft SharePoint Foundation 2010, and Microsoft Project Server 2010) support the 64-bit edition of Windows Server 2008 with Service Pack 2, and Windows Server 2008 R2. For more information, see the following resources:
- For click-to-run scenarios, the supported version is Office 2010 32-bit (WOW64) on computers that run the supported 64-bit editions of Windows operating systems.

I have downloaded the beta (ProfessionalPlus.exe). The only reason I want to beta test is to explore the native 64-bit version of office. I have no interest in the 32-bit version (I will continue using Office 2007 for that).
My problem is: how the heck do I get my hands on the 64-bit install? Does the file I downloaded include both install types? I currently have Office 2007 on my test box, and when initializing my 2010 install, I am not offered the choice to install 64 versus 32-bit version. The documentation at:
http://www.microsoft.com/downloads/details.aspx?FamilyID=600c2142-abc3-4fea-9271-0c326c45dc8f&displaylang=en
is informative, but it is also rather cryptic in that it does not clarify exactly how one can obtain/install the 64-bit Office 2010. The article only explains the scenarios vaguely and explains advantages/disadvantages of the 64-bit version.
Once you tell me how to obtain/install 64-bit, I have another question: does the 64-bit version come with 64-bit ODBC driver versions?
Thanks for your time on this.

Sunday, February 28, 2010 2:57 AMI can't even install the 64 bit version to try it. I expect it to be problematic, it is a beta but it will not install because the installer still sees some remnant of 32 bit office 2007.
Just saying, you may recomend the 32 bit version but I thought we were beta testing it. -

One of the MS articles above confirms that even the Sharepoint IE datasheet controls which come with Office will not work in the x64 version. I found that out the hard way and had to uninstall it and use x86. I can understand 3rd-party products having a problem, but come on, anything that's in Office kinda has to be compatible, don't you think?

Tuesday, March 02, 2010 4:12 PMIMHO, sharepoint not working is a good thing. j/k, I am sure it has it's uses.

Try installing the 2007 Office System Driver: Data Connectivity Components after you have installed Office 2010 64-bit on the client machine. This should provide you with the edit in Datasheet functionality. Let us know how it works out.

Monday, May 10, 2010 5:59 PMI don't have Office x64 any longer, but I recall installing what you mention on an Office-less system once, hoping that it was a way to be able to use SP datasheet controls without having to install Office on the client. It turned out that it wasn't.

Monday, May 10, 2010 6:51 PMI have download it for the 32 bit OS but the net was not set on it

Tuesday, May 11, 2010 6:11 PMThe workaround only works if Office is installed on your system.

Does this help?
Will a 64-bit version of the Office 2010
product be available?Yes, 64-bit Office 2010 product upgrades will be available. However we strongly recommend most users install 32-bit version of Office 2010 on both 32 and 64-bit Operating Systems because currently many common add-ins for Office will not function in the 64-bit edition. The 64-bit installation of Microsoft Office 2010 products will be available for users who commonly use very large documents or data set and need Excel 2010 programs to access greater than 2GB of memory. There may be technical issues with the 64-bit version and in order to install a 64-bit version of Office 2010 product users must have a 64-bit supported operating system on their PC.
The only thing that is static in life is the change... -

A KB article is now available that discusses using the 2007 Office System Driver: Data Connectivity Components as a workaround to provide the edit in Datasheet functionality. Please see http://support.microsoft.com/kb/2266203 for more information.
