A while ago Microsoft announced the end of life for the InfoPath product in the Office suite. Since that time, Office 2016 has been released, and there’s still a large demand for the InfoPath product by a number of my colleagues and clients alike. Microsoft has not produced a new version of InfoPath for the 2016 office suite, but what they have produced is a version of InfoPath (still 2013) which is compatible with the Office 2016 suite.
Below is a link to the download from Microsoft of the “InfoPath 2013 for Office 365 ProPlus Subscription” product.
This download will allow you to have both a copy of Office 2016 together with InfoPath 2013. Note that theoretically if you had Office 2013 you could uninstall all but the InfoPath 2013 product and then install Office 2016 and possibly have a working version of InfoPath that way, but I have not tried this approach, as there’s really no benefit to doing this. I have however used the download above, and it works great together with Office 2016.
