Hi Danl42711062, Please try the following steps to set the PDF to open at 100% by default: Go to Edit>Preferences>Page Display>Default Layout and Zoom. If you set it to 100% in preferences, it should apply to all documents every time you open a file. However, if the creator of the file has set a higher zoom setting, Reader in that case would continue to open the file with the same setting. Let me know how it goes. Thanks, Supriya
