As it stands, Microsoft Office 2010 Standard Edition lacks many key compatibility features with SharePoint Server, while the Editions such as Office Professional and Office Professional Plus offer much more (Microsoft, 2010). One of the most important usability features of compatibility is the ability to manage information inside SharePoint lists and libraries is datasheet view. I know that once this feature is adopted by a user base, it is not something that can be taken away because people rely on on datasheet to manipulate data fast and easy.
Regardless of whether Office 2010 is 64-bit 0r 32-bit, the edition of office must be ABOVE STANDARD. This means that if you have Office 2010 Standard, you DO NOT have datasheet view. I cannot imagine having a SharePoint environment in which I do not have access to datasheet view, and so I would base my decision on which Office Suite to use solely on datasheet view...in other words, Office 2010 Standard is dead to me and I only care about Professional and higher from this point forward.
In the process of upgrading my primary client system to Office 2010 Professional Plus, I also had to decide between 64-bit and 32-bit. 32-bit is still recommended for maximum compatibility with add-ins and third party products, while 64-bit is intended for individuals who are working with large amounts of data (Microsoft, 2010). 32-bit is also more convenient to run. Datasheet view is automatically available to use if you have Microsoft Office 2010 (above Standard Edition) 32-bit. Datasheet view isn't automatic for 64-bit though, as evident by this error message:
Error: "The list cannot be displayed in Datasheet view for one or more of the following reasons:..."
To make my life as complicated as possible, I decided to go with 64-bit. So, how is does 64-bit Office 2010 complicate the datsheet view capability? Well, I quickly learned that as of the 64-bit flavor of Office 2010 has additional requirements in order for datasheet view to be available. After installing the 64-bit Office suite (remember, must be Standard Edition or higher), you must do one of the following, in order to avoid the obnoxious pop-up error above:
A. Download and install the 2007 Office System Driver for Data Connectivity Components.
or
B. Install the 2007 SharePoint Services Support, which is available on the Microsoft Office 2007 installation media.
