MS Office 2013 - 64 bit

Pokud uvažujete o nasazení MS Office 2013 ve verzi 64-bit, je dobré se nejprve seznámit s následujícím.

Systémové požadavky:
- 64-bit Office běží pouze na os s 64-bit Windows
- Nelze současně instalovat 32-bit MS Office a 64-bit MS Office
   (např. 32-bit MS Office 2010 a 64-bit Office 2013)
- Při přechodu na 64-bit verzi je nutno nejprve provést odinstalaci a znovu instalaci MS Office 2013

32-bit Office is recommended for most users
We recommend the 32-bit version of Office, because it is more compatible with most other applications, especially third-party add-ins. This is why the 32-bit version of Office 2013 is installed by default, even on 64-bit Windows operating systems. On these systems, the 32-bit Office client is supported as a Windows-32-on-Windows-64 (WOW64) installation. WOW64 is the x86 emulator that enables 32-bit Windows-based applications to run seamlessly on 64-bit Windows systems. This lets users continue to use existing Microsoft ActiveX Controls and COM add-ins with 32-bit Office.
64-bit Office has advantages that benefit only specific kinds of users and workloads
There are several cases in which you should consider deploying 64-bit Office 2013. Here are several examples:
Excel expert users who work with complex Excel worksheets can benefit from using 64-bit Office 2013. This is because 64-bit Office doesn’t impose hard limits on file size. Instead, workbook size is limited only by available memory and system resources. On the other hand, 32-bit Office is limited to 2 gigabytes (GB) of virtual address space, shared by Excel, the workbook, and add-ins that run in the same process. (Worksheets smaller than 2 GB on disk might still contain enough data to occupy 2 GB or more of addressable memory.) You can learn more in Excel specifications and limits and Data Model specifications and limits.
Users who use Project 2013 also benefit when they use Project files over 2 GB, especially when they are dealing with many subprojects to a large project.
In-house Office solution developers should have access to the 64-bit Office 2013 for testing and updating these solutions.
Office 2013 offers enhanced default security protections through Hardware Data Execution Prevention (DEP). (DEP) is a set of hardware and software technologies that perform additional checks on memory to help prevent malicious code from running on a system. For 64-bit installs, DEP will always be enforced for Office applications. On 32-bit installs, you can configure DEP by using Group Policy settings.
