Yes, your discovery is right and valuable, the workaround that using old SearchOCR.adml as a substitute is also good. I have submit this situation to Microsoft via our channel, let’s wait for update.
For now, you can try this method, come from a forum user named Chase Roth:
I manually edited the "...\en-US\searchocr.amdl" file and added the value from the previous version.
Search for these lines about line 25 (if you are not wrapping lines):
<string id="OCR">OCR</string>
<string id="OCREveryPage">Force TIFF IFilter to perform OCR for every page in a TIFF document</string>
then add the line given below between them:
<string id="OCR">OCR</string>
<string id="Win7Only">Microsoft Windows 7 or later</string>
<string id="OCREveryPage">Force TIFF IFilter to perform OCR for every page in a TIFF document</string>
...and no more errors! I am no expert so I don't know if this could cause any issue , but I don't think so as it is just to localize the variables into the language of choice.
