This article contains information about how to use Microsoft Office 2013 suites and programs on a computer that is running another version of Microsoft Office. This article also provides advice to help prevent conflicts between different versions of Office.
You can install and use more than one version of Microsoft Office on a single computer. For example, you can install and use both Microsoft Office 2013 and Microsoft Office 2010 on the same computer. However, we do not recommend this.
Note We do not support the use of multiple versions of Office in versions of Windows that have Terminal Services enabled. If you want to run multiple versions of Office in Windows, disable Terminal Services.
VirtualizationTo avoid the issues discussed in this article, one or more of the Office products can be deployed in a virtualized environment by using one of the following solutions.

Microsoft Application Virtualization (App-V) can enable incompatible applications to run on the same instance of the operating system. The applications are centrally managed services that are never installed, minimize conflicts, and that are streamed on-demand to end-users.
For more information about App-V, go to the following Microsoft website:

Office 2013 Resource KitWindows 8 and Hyper-V
Hyper-V is included with Windows 8, therefore you do not have to download and install it.

Overview of Hyper-V
Installation orderIf you want to install and use more than one version of Office on the same computer without virtualization, use the following order.
You must install the earliest version of Office first. For example, if you want to use both Office 2007 and Office 2013 programs on the same computer, install Office 2007 first. You must use this order because of how registry keys, shared programs, file name extensions, and other settings are managed for each version of the Office suites and programs.

You cannot run the 64-bit version of any Office 2013 suite or program when a 32-bit version of Office is installed on the same computer. The Setup program will detect that you have previous 32-bit versions of Office programs on your computer, and require them to be removed before you can install Office 2013 64-bit.
Note: This statement applies to the MSI, Click-to-Run (C2R), and App-V deployment types.
Office Bin folder locationWhen you install Office 2013 suites or programs, the Setup program uses the Program Files\Microsoft Office folder as the default folder on a 32-bit version of Windows, or the Program Files (x86)\Microsoft Office folder as the default folder on a 64-bit version of Windows.The Office Bin default folder in these versions of windows are Program Files\Microsoft Office\Office15 and Program Files (x86)\Microsoft Office\Office15 respectively. The Office Bin folder is the folder in which the Office executable files are installed. This location provides a better user experience for those who want to use multiple versions of Office on the same computer. Be aware that you cannot change the name of the Office Bin folder.
Start menu shortcutsFou can use the Office Customization Tool to specify a different location for the Office 2007, Office 2010, and Office 2013 shortcuts. To access the Office Customization Tool, run the setup /admin command in the root directory of the Office 2013 CD at a command prompt:
Note The Office Customization Tool is available only for non-retail versions of Office 2007, Office 2010, and Office 2013.
For more information about the Office Customization Tool, go to the following Microsoft TechNet website:

Multiple versions of OutlookOutlook 2013 cannot coexist with any earlier version of Outlook. When you install Outlook 2013, the Setup program removes any earlier versions of Outlook that are installed. The Setup program removes these versions of Outlook even if you select the Keep these programs check box in the Removing Previous Versions dialog box.
Microsoft Office Groove 2007 and Microsoft SharePoint Workspace 2010
Microsoft SharePoint Workspace 2010 cannot coexist with Microsoft Office Groove 2007. When you install SharePoint Workspace 2010, the Setup program removes Groove 2007. The Setup program removes Groove 2007 even if you select the Keep these programs check box in the Removing Previous Versions dialog box.
Multiple versions of WordIf you have two versions of Word installed on the same computer, you experience a delay when you start Word 2010. This behavior occurs because Word 2010 automatically registers itself on the computer.
You can bypass this registration to enable Word 2010 to start faster. However, we do not recommend this because Word may not function correctly if it cannot register itself.
Important This section, method, or task contains steps that tell you how to change the registry. However, serious problems might occur if you change the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you change it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

Office files in Microsoft Windows ExplorerWhen you double-click an Office file in Windows Explorer to open the file, the following rules apply. These rules also apply when you double-click the Office file in the Recent Documents folder in Windows.

You may have to repair some or all Office products after you install a software update to restore the file associations.

Repair or remove your Office programs
Windows 8 steps to repair or remove Office 2013:
Repair your Office programs
Office OLE objects in other programsIf you insert an Office object into another program on a computer that is running multiple versions of Office, the latest version of the program is used. For example, if you insert a Microsoft Excel worksheet object into a Word document, the latest versions of Word and of Excel are used. This may cause problems if you share the container file with users who are not using Office 2010 programs.
Shared programsIf you install the different versions of Office in the order that is described in the "Installation order" section, you should not experience any problems when you use shared programs such as Equation Editor and Clip Gallery. However, the Object dialog box may display more than one entry for each shared program. This behavior occurs because multiple versions of the shared program are installed on the computer.
Windows Installer messages in WordIf you have multiple versions of Word installed on the computer, the Windows Installer may start when you start Word 2013. Additionally, a message that states that the Windows Installer is preparing to install Word may be displayed before Word starts. This occurs when the version of Word that you start is not the one that is registered. The repair operation can take several minutes to finish.
Windows Installer messages in AccessWhen you start a version of Access on a computer that has multiple versions of Access installed, the Windows Installer may start, and a message that states that the Windows Installer is preparing to install Access may be displayed before Access starts.
Every time that you start Access 2003, Access 2007, or Access 2010 after you use Access 2013, the Windows Installer repair operation registers that version of Access. Similarly, the Windows Installer repair operation registers Access 2010 every time that you start it after you use an earlier version of Access. This does not occur when you start Access 2002, nor does it occur when you start the same version of Access again.
