Hello all!
This is a very strange problem

(to me). A document saved as .docx in Word 2016. 64bits is not allowing Edit Data for charts.
The Charts were created directly from Word (and were embedded excel files not linked) and now clicking "Edit Data" or "Edit in Excel" doesn't do anything.
When the same document is opened through the Home Network on a different PC (also using Word 2016), both "Edit Data" and "Edit in Excel" work just fine, and a window pops up for editing the data.
Initially the documents were created in Word 2013. 32 bits.
This issue appeared after the latest Windows 10 update today, 2.12.2017. The other PC (on which the Edit Data works) is also on Windows 10, but without the recent update.
I would very much appreciate your help and input!
