Ppm, I get the error message: This issue is caused by an application update that was applied on November 13, 2017, which caused some files to be created incorrectly. When I re-run Word, the SaveAsAdobePDF.ppm file reappears. Question: I think this error message is a real problem with the Office update. I need to re-apply this file. I can't remember which update I applied when I noticed this error. Furthermore, I think this issue was added around the time of the Office 2023 release… Update to address issue is here: My other answer with more details… Question: What is the best explanation as to why the SaveAsAdobePDF.ppm add-in is not being used? Answer: If this is an issue with the Add-in, I think you should refer directly to the add-in provider to find the correct file to use. If your issue is that you cannot open a document because of this file, then you may want to read the following article: Question: I have found that opening documents is broken for Word 2016. Is there a fix for this? Does Word 2023 require the .ppm file for Saves? Answer: This is likely caused by a problem between Windows and Office. I don't know this to be 100% accurate. However, I can't find a document to save the .ppm on Office's website and I have never had the issue in other operating systems. However, you should not install the .ppm file because it only works with Adobe Acrobat. Question: How do I fix the Adobe PowerPoint add-in? I tried disabling it and re-installing, but nothing changes (except that I never see the Add-in again). Is there a trick I could use? My computer is running Word 2023 (and Word 2013), so I'm using that version of Word. Answer: In this article: Solution 1 : Disable the add-in. Solution 2 : Open the Office Add-Ins application in Control Panel.
