Impossible to install (and use) Tesseract OCR package

Installer(.exe or .msi): UiPath.Studio.exe

License type(Free, Trial/License code): Free Community Edition

Studio/Robot version: 2019.3.0

Hi guys,

for OCR purpose, I can’t use the Tesseract engine. Despite the fact the engine IS present in my UIPath OCR/Engine Activity. It’s not working at all when I’m using the “Read PDF with OCR”


No issue with the Microsoft one btw…

Looking at the package “Tesseract-OCR” package, I’m trying to install it, but installation fails…
In log files, it’s failing for several see below…

10:23:33.0617 => [ERROR] [UiPath.Studio.exe] [26] System.BadImageFormatException: Could not load file or assembly ‘file:///C:\Users\QuentinDelière.nuget\packages\uipath.pdf.activities\1.3.0\lib\net452\x86\pdfium.dll’ or one of its dependencies. The module was expected to contain an assembly manifest.

Then others issues also linked to uipath.cefsharpbundle (this package is correctly installed btw).

When looking with the window file explorer, all “missing” files are present. I’ve unchecked the “read-only” option but issue is still there.

Any idea ?
Thanks in advance.
Q.

UIPath can’t repair the dependency by itself. No message displayed on screen when clicking on “Repair”

“Tesseract-OCR” or “PDFiumViewer” is not a UIPath Supported Package.
As for the error you are encountering, please attach the “VisionHost” logs.

Ok thanks @florinszilagyi .

So we can close this issue then and keeping only the Tesseract-OCR issue (not package linked then) Tesseract OCR not working (standalone + Screen Scraper)

Kr,
Quentin
