I need the following box unchecked in Preferences: Security (Enhanced) >> Enable Protected Mode at startup. With this unchecked, everything is fine. When the application automatically updates, it checks this box back on. This causes an error with my application. Is there a way to prevent the box from always being turned back on with a new update? This is the 2022 version of Adobe Acrobat Reader on Windows Server 2019. Thank you
Sorry for the delay in response.
Please refer to this article and change the registry setting as suggested:
Registry configuration: Locking enhanced security settings https://www.adobe.com/devnet-docs/acrobatetk/tools/Wizard/security.html
Hope this helps!
