Unable to open a word or excel document in SharePoint 2013

Recommendations / Troubleshooting steps:

a)   Try activating the site collection feature "Open Documents in Client Applications by Default" to force your documents to open on your machine.

b)   Check to see if your settings are configured to allow documents to be opened in browser.

c)   Another thing you could check is IE- make sure you're using the 32-bit version.

d)   Try changing browser file handling settings for web app under Central admin site. (Default value is strict. Try changing to Permissive)

e)   Use different browser. May be Mozilla Firefox

f)    Use different login on your client machine (Not SharePoint login, machine from where you are accessing SharePoint site)

g)   Use different machine

h)   Are the word documents .doc or .docx? must be docx to open via web.

i)     Verify if you using the office web apps for SharePoint 2013

j)    If you ever get the error “Word experienced an error trying to open the file” or any other error messages while opening the word documents on the SharePoint 2013/2010, it may be because your Office 2010/2013 protected view is enabled

Note: there is a known issue if you have Office 2010 and Office 2013 installed on the same computer.
