How to check MS Office Version and MS Office bit version?

• Open any MS Office application, like Excel, Outlook, Word etc.
  (I am using the example of MS Excel)
• Click on “Blank workbook“
• Click File
• Click on Account

On the right side you will see screen similar to below one

1. MS Office Name
2. MS Office Version
3. Owner of MS Office
4. The other applications which MS Office contains
5. More information about Support, Product ID, etc.

If you want to know the Bit Version of your MS Office

• Click on About Excel (5th option)

In my case it is 32 bit version of MS Office.
