Solution: Revert to Adobe PDF plug-in Choose your browser and system: Filter by: Manually change your browser preferences so that it uses the Acrobat or Reader PDF viewer. The download is available from the Adobe web site, here: (2) Adobe Reader's web browser intergration may be damaged. Click Start > Apps & Features, select the Adobe Acrobat or Adobe Reader version that is installed, click "Modify" and then "Repair". Please see this Adobe page for additional troubleshooting suggestions: Alternatively, you can uninstall and reinstall Adobe Acrobat or Adobe Reader. (3) Open Adobe Reader and leave it open in the background while running dtSearch Desktop. (4) In dtSearch Desktop, click Options > Preferences > PDF View Options and un-check the box to "Use dtSearch Desktop toolbar to navigate hits in PDF files". This changes the mechanism used to load PDF files in dtSearch Desktop and sometimes resolves cases where the Internet Explorer security settings prevent the standard mechanism from working. PDF files appear normally but without hit highlighting To make hit highlighting work in Adobe Reader or Adobe Acrobat DC, X or XI, you will need dtSearch version 7.71 or later, and you will also need a dtSearch plug-in for Adobe Reader or Adobe Acrobat. For information on this plug-in, please see To get the plug-in, install dtSearch version 7.71 or later, run dtSearch Desktop, and click Options > Preferences > PDF View Options > Configure Plug-in. If you have the plug-in installed and PDF highlighting still does not work, you may have Adobe Reader "Protected Mode" or "Protected View" enabled. To change this setting, run Adobe Reader and click Edit > Preferences > Security (Enhanced). ![]() ![]() (1) Disable Protected Mode or Protected View in Adobe Reader, or When Protected Mode or Protected View are enabled, Adobe Reader blocks the plug-in.

This complements Microsoft's own Control Flow Guard (CFG).(2) Click the "Trust this host" banner that pops up the first time you open a retrieved PDF file. Adobe Acrobat and Acrobat Reader run as a plug-in to display PDF files in a web browser. This includes compile-time mitigations such as Intel's new Control Flow Enforcement Technology (CET), enabled in Microsoft Edge with update 94 for CPUs that support it. "Alongside PartitionAlloc, we ensured that a suite of additional technical countermeasures, also already used across Microsoft Edge, were compatible with the new PDF stack. Microsoft also details its own contributions to Edge security mitigations. "This unique heap implementation provides a rapid understanding of vulnerabilities and a strong layer of protection that the new PDF stack will benefit from," Microsoft says. All of these help mitigate memory flaws like use-after frees, but they also create a performance overhead. This includes using security features developed by Google's Chromium team to mitigate C++-related memory flaws, including the relatively recent add-ons for MiraclePtr and heap memory scanning, as well as PartitionAlloc, Chromium's memory allocator. It says the Microsoft Edge Vulnerability Research team was "heavily involved" in the process of bringing the Acrobat engine into Edge. Microsoft detailed some of the work it's done to secure the browser's PDF stack. Turner claims that "using the free PDF experience with the Adobe engine will not allow Adobe to collect any data from you." ![]()
