Acrobat Standard DC "Unable to locate the Paper Capture recognition serves."

I recently updated my version of Acrobat Standard DC to continuous release version (which currently shows version 2020.006.20034 is installed).  While it updated without incident, I am no longer able to run text recognition on any document, getting the error "Acrobat could not access the recognition service because: Unable to locate the Paper Capture recognition service.  Your installation may be corrupt."

I have tried the workaround located here (https://helpx.adobe.com/in/acrobat/kb/acrobat-could-access-recognition-service.html).  I have tried a repair installation.  I have tried uninstalling and reinstalling, and I have tried uninstalling, running the Acrobat cleaner tool (every version, starting with the DC version and working backwards) and then reinstalling.  I have tried all of these steps several times, using every variation that I have found in this forum or online, but nothing fixes the problem.

Under Help>About Adobe Plug-ins, it shows that PaperCapture version 20.6.20034.366983 is loaded and certified.

I am out of ideas.  Does anyone else know how to fix this?  I only have it for it's OCR abilities, this is killing me.

Thanks.

I finally got the problem solved.  While I was waiting for feedback on how our software licenses worked with VMs, I decided to try on more route. I'm sure this wasn't the most efficient route to the solution and a lot of the step probably were not even necessary, but I wanted to post it in case it could benefit someone else searching for the same solution.First, I started out by searching my hard drive for some of the files that were in the PaperCapture folder (under plugins). It found almost al...

Hi all,

after experiencing the same error on a fresh install of Acrobat Pro 2017 and reading all the explanations and "Trial and Error" solutions, I digged a little deeper...

 

My results:

Acrobat is searching the files (idrsasian215.dll, idrskrn15.dll, idrslex15, idrsocr15.dll, idrsprepro15.dll) in the wrong location (C:\Program Files (x86)\Adobe\< Adobe product e.g. 'Acrobat 2017'>\Acrobat\plug_ins) and this is presumably a software bug!

It then continues to search for the files like everywhere, one of it, it found in my HP printer directories, but finally Acrobat fails.

There are registry entries for some of the needed&searched for files, pointing to the correct location of the dll files, but they seem to be ignored (Acrobat never looks there).

You can check for yourself using a tool like Process Monitor provided by Microsoft for free. You should set the filter to

"Path begins with C:\Program Files (x86)\Adobe\< Adobe product e.g. 'Acrobat 2017'>\Acrobat\plug_ins"

and monitor the "File Access" only (the icon with the magnifying glass), otherwise you really get a lot of log entries.

You will find something like this (second entry, first is just for comparison):

11:43:10,0464469	Acrobat.exe	8376	CloseFile	C:\Program Files (x86)\Adobe\Acrobat 2017\Acrobat\plug_ins\PaperCapture\OCRLibraryInf.dll	SUCCESS	
11:43:10,0467578	Acrobat.exe	8376	CreateFile	C:\Program Files (x86)\Adobe\Acrobat 2017\Acrobat\idrskrn15.dll	NAME NOT FOUND	Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a

After copying all the "not found dll files" from their correct loaction to the "wrong", but used location, your Acrobat will work (at least in my case ;-).
Be aware that the problem is, that Acrobat (if there will ever be an update for the not cloud Acrobat version - they are not so in favor these days), will most likely update the files in the wrong place :-D.
Maybe you can get around by making hardlinks to the files in the original place (yes, Windows can also do this), but most likely this will break the Adobe update process (this "update process", which drove me crazy with my previous Acrobat XI version).

 

Kind regards

 Tom

Tom's recommendation for setting the path filter in Process Monitor is a great tip, and helps to narrow things down a lot faster.

Unfortunately, he is also correct to beware of updates.  After my previous solution, everything ran great for about two months, then the OCR stopped working and the error reappeared.  Since I hadn't updated or installed any other softwere since the previous fix, I immediately suspected Abobe DC updates.  Sure enough,  the 9 "idrs" dll files from the Paper Capture plugin folder were newer than those I had copied before to the Program Files (x86)\Adobe\Acrobat DC\Acrobat folder.  After copying these once again, OCR began functioning.

 

Prior to this, I did check for updates and ran a "Repair Installation" in Acrobat with no luck.  While researching the issue, I found that it seems to have existed for at least the past few versions.  Over all these years, I am amazed that Adobe hasn't fixed the core issue -- they have just posted an overly simple "work around" that was insuffient in my case.  I expect better.

Same problem after clean install of most recent Acrobat Pro DC  v2020.012.20043 on Windows 10-Pro.  I copied all the irds*.dll files from C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\plug_ins\PaperCapture\iDRS15  into C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\ 

 

And it just worked.  Thank you SO much.   Adobe should fix this.

Thanks to all here for, albeit temporary, solutions to this problem.  You all saved my hieny today. I appreciate you all but have to say pretty sick of having to spend an inordinate amount of time to fix a recurring problem that Adobe can't or won't fix.  Even using Adobe's help/fix requires me to uninstall, reinstall, and move files around (that are re-entered in the wrong place again as soon as there's an update) and repair their damage.  Searching for a new PDF editor that doesn't charge me to continually fix their problems.
