Template M2doc Word problem

I want to create a template, but my file does not open in Capella so I do not have the ctrl + F9 command.
I have the Word 2016 version.
I really realize the process of inserting the extension, Help / Install New Software and select the corresponding Zip.
I thank you in advance.

Hi Sebastien,
To open a word document from Eclipse, right clic on your template and select open with system editor. Alternatively, you can also direcly use Word to open it.
