See sample screen below:
A - To resolve this issue, you need to start up Microsoft Excel 2013 and go to "File" -> "Options" -> "Advance." Scroll down to the "General" section. Un-check the option "Ignore other applications that use Dynamic Data Exchange (DDE)." See sample screen below.
Just for your information, this flag is not set by default when Excel 2013 is installed.
