Cause

If you find the error "Faulting application name" in Event Viewer, Adobe Acrobat is crashing due to an incompatibility between the program's "Protected Mode" settings and the Engagement or Workpaper Manager plug-in for Acrobat. As stated in our system requirements, Engagement and Workpaper Manager does not support Protected Mode in Adobe.

Resolution

Continue with the article further below for 32-bit Adobe Acrobat. For 64-bit Adobe Acrobat, follow the article below.

The CCH® ProSystem fx® Engagement or Workpaper Manager add-in is installed but does not display in Adobe Acrobat DC 64-bit.

To resolve Adobe Acrobat/Adobe Reader crashing or not opening due to Protected Mode settings, follow these steps:

Remove the PfxEngagementx.api (for Acrobat) or PfxEngagx.api (for Reader) file from the following location:

64-bit Adobe: ?:\Program Files\Adobe\Acrobat XX\Acrobat\Plug_ins, where "?" is the storage drive that Adobe is installed to, and XX is the version of Adobe.
32-bit Adobe: ?:\Program Files (x86)\Adobe\Acrobat XX\Acrobat\Plug_ins, where "?" is the storage drive that Adobe is installed to, and XX is the version of Adobe.

Turn off protected mode in Adobe. For steps, please refer to the following Adobe articles below.
- Protected View Feature for PDFs
  - When working in a terminal server environment or if you wish to push the setting, please reference Adobe's documentation below.
    - Protected Mode functionality.
  - The above documentation lists examples for Acrobat 10. The same key works for DC simply replace 10.0 with DC.
1. Adobe > Edit > Preferences > Security (Enhanced).
2. Under "Sandbox Protections" > uncheck "Enable Protected Mode" at Startup (preview).
3. Under "Enhanced Security" > uncheck "Enable Enhanced Security."
Only for 32-bit, replace the PfxEngagementx.api or PfxEngagx.api.
- How can I manually install the CCH® ProSystem fx® Engagement or Workpaper Manager plugin for Adobe Acrobat or Reader?

If this is occurring to multiple profiles on a terminal server, you will need to make the changes on each profile, as Adobe doesn't save the preferences from one profile to another or you can use Adobe's article on how to change the registry key to make the changes.
