I also wanted to use this for the same scenario.
I did an experiment to check if I can check the command line that can be seen when running AcroTextExtractor.exe .
I took a large PDF file and opened it in Adobe Acrobat Reader DC version 2018.009.20050. Then I saved it as text (File | Save as other text), and when Reader generated the text file (successfully), I checked all the running processes in the task manager, sysinternals Process Explorer and from WMI to Powershell.
Unfortunately, I could not find the process started using the path, including AcroTextExtractor.exe ; so I could not capture the command line.
It could be a red herring.
