I'm sorry about the issue. Do you have Microsoft Office Word / Excel 2003, 2007, 2010, 2013, etc.?
Can you right-click on the Start button at the lower left, then click on Control Panel, then click on Programs -> Programs and Features
, then select the Microsoft Office item there, then change / repair it
, then check; if needed, restart the computer and check.
Please let me know. Thank you.
