Saving a file as PDF in MS Word 2007

Due to the forced updates, and my computer refusing to update past 1803 for completely unknown reasons, I had to do a fresh install, which was an adventure unto itself but I digress, and had to reinstall all of my apps.

This includes my copy of MS Office Home and Student 2007, which I have been using happily since 2007. The problem is, I created a new document, saved it as a doc file, and then tried to save a 2nd copy as a PDF, but that option is gone from my save as list. I have literally done this dozens of times in the past. I have never installed a third party software to help Word do this, it was just under the Save As menu. I have also had my system crash in the past and reinstalled MS Office and was still had the ability to save the file as a PDF.

Anyone else run into this or know a solution other than start working with the Google products which allow me to do this easily, and can also convert the files I recently created in Word with a few simple steps?

Thanks!
