I miss the simplicity of having a dictionary already available in earlier versions of Word.
After opening Word 2013 I could see that I was successfully signed in. When I try to load my dictionary from the Office Store I receive ‘Cannot connect to catalog’.
In the upper right corner I would see a triangle filled with yellow highlight and an exclamation mark in the center of the triangle followed by:
“To use this function you’ll need to sign in with a Microsoft Account.”
I thought that was interesting because I'm already signed in with a Microsoft Account, and I'm signed into Word 2013.
Since I was signed in to Word 2013 already, I looked for a way to sign out and back in again but could not find one using office help.
When I clicked on ‘sign in’ I would get the same message that I should sign in again YET – there appeared to be no way to sign in again without the same failed situation.
I clicked on the down-arrow to the right of my username and then clicked on
switch user. This signed me out of Word 2013. I then signed back into Word 2013 using the very same Microsoft Account username and password and Wham.
Now when I click on Insert > My Apps, I see my Merriam-Webster Dictionary app appear.
I clicked on the Merriam-Webster Dictionary Icon and the dictionary loaded into Word 2013.
All seems well now.
P.S. – Prior to loading my dictionary into Word 2013, I had to sign in to Office.Com/MyAccount, go to the Office Store and add the dictionary of choice from the Office Store to my account. This made my dictionary available as an app for loading into Word
2013.
