Unable to reproduce the issue on Windows-10 using chrome stable M52-52.0.2743.116  by following steps mentioned in the original comment. Observed the PDF files are able to open in chrome as expected.

thicks@ - Could you please recheck this issue by creating a new profile under chrome://settings with no apps or extensions in your browser. If issue still persists please navigate to chrome://plugins and make sure that PDF plugin is enabled.

Thanks!

brajkumar: It's the first link, http://wwwimages.adobe.com/content/dam/Adobe/en/education/pdfs/visual-communication-cs6-exam-prep.pdf that reproduces the problem.

In my queue it goes. If anyone is interested in exploring chrome/browser/ui/pdf/ (yep, another stash of PDF related code!) then feel free to take this bug from me.

Notes:
- The Chrome PDF Plugin correctly detects the PDF has an unsupported feature.
- The plugin + PPAPI correctly plumbs a notification to PDFHasUnsupportedFeature()
- ??? (I don't have Acrobat Reader installed at the moment)

It could very well be the same that the Acrobat Reader integration code broke in some way, or that we don't integrate with Reader DC correctly because it did not exist when the relevant code was written.

Can I just say that some of your comments are hilarious...love it!  :)  Thanks for checking into this.

My queue is too long so I'm not going to get to this any time soon. Hopefully someone else CC'd can take a look.

hnakashima@ for PE triage.

The PDFs are not accessible anymore. I'm pretty sure we ignore the PDFHasUnsupportedFeature() notification, though.

Does anyone have a file that triggers this?

We don't have access to the file to reproduce anymore, and I haven't other reports similar to this.

The line "2. Receive message that need Adobe Reader 9 or later installed" makes me suspect it was an XFA document. Even if it wasn't, this would probably not be a PDF Plugin bug.
