Issue:

You receive the following error when starting Adobe Reader XI:

The OnePlaceDocs Plugin failed to run the broker in protected mode.

Reason:

The user is running Adobe Reader (not Acrobat) XI in Protected mode, with a required file missing.

Check to see if OnePlaceDocsAdobePlugin.exe exists in C:\Program Files\Adobe\Adobe Reader 11.0\plugins\pi_brokers\

Solution 1:

Please check that it has not been removed or quarantined by an antivirus program.

If so, please restore this file.

Solution 2:

If the file is not able to be restored from quarantine, two options are available:

1. Uninstall and reinstall OnePlaceDocs, excluding OnePlaceDocsAdobePlugin.exe from the antivirus before running Adobe Reader;
2. Disable Protected mode in Adobe Reader
