How to determine which version of Microsoft Office 2013/2010 is installed?

Starting version 2010, Microsoft Office  comes in 32-bit version as well as 64-bit version. While the 32-bit version can be installed on 32-bit as well as 64-bit version of Windows, the 64-bit version can be installed on 64-bit version of Windows only.

If you are running a 64-bit version of Windows, you can use the following steps to determine if you are running a 32-bit version or 64-bit version of Microsoft Office:

PowerPoint 2013 PowerPoint 2010
  1. Select the File tab or press Alt+F key combination.
  2. Click Account button in the left pane.
  3. Click About PowerPoint button in the right pane.
  4. Look at the first message in the dialog box. On 32-bit version, it reads something like:
    Microsoft® PowerPoint® 2013 ..... 32-bit

    On 64-bit version it reads something like:
    Microsoft® PowerPoint® 2013 ..... 64-bit
     
  5. Click OK button to dismiss the dialog box.
  1. Select the File tab or press Alt+F key combination.
  2. Click Help button in the left pane.
  3. In the right pane, look for Version under the About Microsoft PowerPoint section. On 32-bit version, it reads something like:
    Version: 14.0.nnnn.mmmm (32-bit)

    On 64-bit version, it reads something like:
    Version: 14.0.nnnn.mmmm (64-bit)
