This article will help you fix the Adobe “There was an error opening this document. Access Denied” error when attempting to check out a file from Revver
The error appears to stem from a setting in Adobe reader, then a configuration issue with Revver. Please read note at the bottom of this article.
1. Open Adobe PDF viewer, ‘select’ Menu & Preferences
2. ‘Select’ Security (Enhanced) & ‘Uncheck’ the field “Enable the Protected mode at startup”
3. ‘Select’ OK and close Adobe and retry to check out the file from Revver
Note: Protected Mode is Adobe's primary defense-in-depth security strategy for mitigating and preventing security vulnerabilities. It protects you by limiting what malicious files can do and access. Protected Mode is enabled by default in Acrobat Reader. We don't anticipate any issue, but disabling this option is done at your own Risk.
