Hello, Is there a way to default Acrobat DC to show the Ruler and Guides on startup, instead of having to select it every single time?
Hi TownofDerry ,
I want to mention that currently there is not an option to view Rulers and Guides on startup by default, however you can press Ctrl+ R on your keyboard to view Rulers easily. You can also request for this feature here : Feature Request/Bug Report Form
Acrobat DC update with a preference to always show rulers is now available, read more here: What's new in Adobe Acrobat DC. This update will be automatically applied to all Acrobat and Reader users in the coming days. You may also update to the latest release by opening the application and going to Help > Check for Updates.
Release notes for today's release are here: 17.012.20093 Planned update, August 8, 2017 — Acrobat and Adobe Reader Release Notes
Please try it out and let us know your feedback.
