Cannot Move Custom Office Templates folder in Office 2013

Do you have a C:\Users\[User Name]\AppData\Roaming\Microsoft\Templates folder?

If you do not see the AppData folder, which is normally hidden, in Windows Explorer, expand the Organize drop down and click on Folder and search options and go to the View tab of the Folder Options dialog and select the radio button for "Show hidden files, folders, or drives".  While the it is also a good idea to uncheck the box for "Hide extensions for known file types"

If you don't have the Templates folder in that location, you could create one.   Then, with Word not running, you could move anything from the C:\Users\[User Name]\Documents\Custom Office Templates folder into the C:\Users\[User Name]\AppData\Roaming\Microsoft\Templates folder and then delete the Custom Office Templates folder.

Then in Word, go to File>Options>Advanced>General>File Locations and click on the User Templates item and make sure that it is pointing to the C:\Users\[User Name]\AppData\Roaming\Microsoft\Templates folder.
