Changing "Confirm before tagging" setting via Registry

[BoogieFLT]

Summary : need to change "Confirm before taffing document" setting via Registry keys.

I am working on a deplyable Bot that will automate some tasks in a PDF using Winium. In order to have access to the UI elements within a PDF, I first need to uncheck the "Confirm before tagging document" option found in Preference > Reading > Screan Reader Options > "Confirm...".

In order to make this Bot deployable to all machines, I would need to be able to change this setting programatically, ideally through the windows registry. But I can't seem to find that setting anywhere.

I looked in the Adobe regristry reference... but found nothing 

(https://www.adobe.com/devnet-docs/acrobatetk/tools/PrefRef/Windows/index.html)

Please let me know if there is a solution to this.

Found it : HKEY_CURRENT_USER\software\Adobe\Acrobat Reader\2017\Accessibility\bCheckReadMode

For some weird reason the UI tree within the doc is still inaccessible when opening the doc until I open and close the preference though...

How did you find  it? What document did you used to verify this?

I would also check in bCheckReadMode depends on other keys that also may need to be modified.

I ended up looking through all the keys I could find and testing any that had a name and a locTion that might have something to do with what I was looking for... long and frustrating process.

To verify I just closed the acrobat, changed the setting in the registry. Opened acrobat again and looked at the settings in preferences to see if they changed. They did.

hope this helps.
