How can I tell whether I'm running a 32-bit or 64-bit version of Microsoft Office?

Some software that Liberty University provides are plug-ins for various Microsoft Office programs. Selecting the correct version for these files will ensure they work properly within Microsoft Office.

For Windows:

The following will walk you through how to find the version of Office you are running for Office 2013 & 2016:

  1. Start a Microsoft Office program (Word, Excel, Outlook, etc., the example below is shown in Word).
  2. Click the File tab in the ribbon.

  3. Then click Account.
  4. On the right, you should see an About button. In this example, we see About Word.

  5. The following screen will present you with the version of Office that you are running.


For Office 2010:

  1. Click File.
  2. Click Help in the left column.
  3. From here, you'll see About (Microsoft Word, Excel, PowerPoint).
  4. Finally you'll see Version which lists the version that you are running.


For Mac:

The following steps will walk you though finding what version of Office you have installed on OS X:

  1. Open your Office Software (Word, Excel, PowerPoint).
    Note: We will use Word in this example.

  2. Click on the Word on the Menu Bar.
  3. From here, click on About Word.

  4. The following screen will show you what version of Word you are using.

  5. Versions 15.24 and newer are running 64-bit Office.


You may not necessarily be using a 64-bit version of Microsoft Office even if you are using a 64-bit version of  Microsoft Windows or Mac OS X. Click on the following link for more information on finding the version of Office: About Office: What version of Office am I using?
