Application error 0xc0000409

Hello,

I've experienced this within Adobe Reader XI and DC 2015.017.20050 on Windows 7

Typically this is experienced when opening PDF's through other programs (mostly IE or attachments with Outlook), but this has been experienced by opening Reader directly. The typical behavior is that someone attempts to open the PDF, it will fail returning the "The exception unknown software exception (0xc0000409)" and so on. On a second attempt, it goes through without incident and it appears that re-opening additional times after that will not produce the original error. This is typical, but I can't say this is consistent.

I've witnessed this myself on multiple computers with nothing appearing to link them regarding configurations, age, or even workflow. I've done repairs, uninstall/reinstall, reinstalled 2013 C++ runtimes. Disabling Protected Mode at startup did not change anything. I've purged the current_user registry entries for the reader portion of the trees and let them regenerate. I've tried updates to DC, which aren't our standard but I wanted to try anything that may work.

I'm out of ideas aside from wiping and reloading the machines without preserving any data from the old. One machine didn't experience problems until it was reimaged, which suggests the idea of corruption created from the USMT. However, these just started like someone turned on a light switch. Patch history doesn't seem to correlate to when the issues started.

Any additional ideas?
