For bit installations DEP will always be enforced, while on bit installations DEP needs to be configured through settings.

With more Outlook customers using bit, rebuilding bit Messaging Application Programming Interface MAPI applications, add-ins, or macros for bit Outlook is the recommended option. But if necessary you can also continue to run them with bit Outlook only. These are primarily bit because no bit versions are available for many add-ins. If your organization needs to continue to use extensions to Office , such as ActiveX controls, third-party add-ins, in-house solutions built on previous versions of Office, or bit versions of software that interface directly with Office, we recommend you go with the automatically installed bit x86 Office on computers that are running both bit and bit supported Windows operating systems.

Choose between the 64-bit or 32-bit version of Office

I know I want the bit version. If you're still not sure which is a better choice for you, see the sections below. Reasons to choose the bit version The benefits of using the bit version of Office are listed below, and there are a few limitations such as not working well with some older version add-ins. Reasons to choose the bit version bit operating system with an x86 bit processor can only install bit Office.

But bit architectures blow right past the 3-GB barrier, and they can theoretically address up to 18 exabytes, or 18 billion gigabytes, of system memory. However, the operating system can also impose a limit on the amount of addressable memory. Those limits, though, are generally much higher than those of the comparable bit versions. Some versions of Windows Server, like Windows Server , are unlimited or nearly so in terms of how much memory they can utilize.

So upgrading to a bit platform will allow you to increase your system memory in most cases. If you are considering replacing your old computers to get better performance, you should probably upgrade to bit computers as long as your mission-critical software is bit compatible. Most computers sold today have bit processors, and more and more software is available in a bit version. But it's important that you make sure all of the software you need to run your organization is available in a bit version so you can continue to use it. For nonprofits that manage many computers, an IT department might have trouble acquiring and supporting new operating systems, drivers, and applications.

Do the differences really matter?

It's expensive enough buying the faster hardware, but getting a second set of software licenses for bit operating systems and applications might be beyond the means of an organization with a limited budget. Furthermore, nonprofits, charities, and libraries often have to deal with erratic IT budgets and donated computers, which means they're more likely to wind up with a mix of bit and bit machines.

In these circumstances, some organizations opt to transition gradually, upgrading hardware first, then operating systems, then applications. Other organizations focus entirely on their servers and leave their desktop machines alone. Servers typically run the most resource-intensive applications, so they see greater benefits from upgrading to a bit platform. If your organization decides that now is the time to embrace 64 bits, keep in mind that most Microsoft products in the TechSoup catalog come with Software Assurance. This program allows you to download and install any version of the software you received from us, so long as you don't install more copies of the software than you have licenses for.

This means you can download and install the bit version of any Microsoft software if you acquired a copy of the bit version with Software Assurance. This benefit applies to Microsoft desktop and enterprise applications as well as to desktop and server operating systems. In summary, every abstruse computer science experiment eventually matures into a problem that individuals and organizations have to deal with.

After years in the early-adopter, cutting-edge stage, bit architectures have become common enough that libraries, charities, and nonprofits have to start deciding when and how they'll transition away from bit platforms. What you ultimately decide to do should be determined by the factors listed above, your budget, and your overall tech needs and goals.
