@adamc12651066 Sounds like Acrobat doesn't want to play with Excel for some reason! I would try and Repair/Re-enable Acrobat's Office Integration (PDFMaker). In Adobe Acrobat, go to Help and click on Repair Installation. When done, restart your computer after the repair is complete. Or in Excl, Go to File > Options > Add-ins. At the bottom, next to Manage, select COM Add-ins and click Go and make sure the "Adobe Acrobat PDFMaker Office COM Addin" (or similar wording) is checked and enabled.
