How to Fix Access Denied Errors When Opening PDF Files
Sometime in early 2019, Adobe released an Adobe Acrobat Reader DC update that disrupts some Syncplicity Windows Desktop Client users. This article is applicable to you if you are getting one of the following error messages when attempting to open a PDF file from the Windows Client-mounted drive.
1-There was an error opening this document. Access Denied.
2-There was an error opening this document. The disk containing this file is not available.
The cause of these errors is an Adobe Acrobat enhanced security setting that forces documents to open in a sandbox. As a result, the document will not be downloaded locally from the Syncplicity cloud.
To fix the problem on Adobe Acrobat Reader DC version 2019 and above, please go to the Edit->Preferences->Security (Enhanced) page and uncheck the setting that says "Run in AppContainer" under the Sandbox Protections heading.
After restarting Adobe Acrobat Reader, you will be able to open PDF files directly from the Windows Client-mounted drive again. Please see this page for more information about the sandbox protections settings: https://www.adobe.com/devnet-docs/acrobatetk/tools/AppSec/sandboxprotections.html
