As an end user, I would like to know why Snag It 2018 was not created with a "share" option to Microsoft Word. Your previous version had this option. I as an end user am requesting to have this option restored in the Snag It 2018 version.
Does your admin deploy Snagit to a large number of people? If so, I wonder if they didn't include that in your settings for some reason??
Or, do you just have one copy that you use? If so, perhaps you can go to this page and download and install the outputs you need? If you have to go through the admin, it could be they have these outputs already and they can "push" it to your installation? Either way, I think you need to start with your admin and let them know you need the output installed and they can decide how that should be done. Let us know if you need more help. Kelly
