After installing the BI Publisher desktop, we sometimes don't see the BI Publisher Plug-in available in the MS Word Ribbon. I have mentioned few steps that needs to be performed to get the plug-in Part - 1 of this post.
Sometimes despite we follow the steps explained in Part - 1, we don't find the plug-in. Here are few more additional steps that I have followed to get it on the .doc file.
I have done this in MSWord 2016 and I believe this will work in other versions as well
1) Open the Word Doc, Click on File -> Options
2) On the Word Options window, select "Add-ins" and click "Go" next to Manage "COM Add-ins"
3) On the "COM Add-ins window, check the box against "BI Publisher Template Builder for Word", and click OK.
4) Now that you should see the BIPublisher plug-in on the menu
Unfortunately, this workaround to get the BI Publisher has to be performed each time you open the word document. There could be a better way of doing this, still searching...
