Libcurl installation problem

[John Finseth]

I'm trying to read text from images with Tesseract. I downloaded from here and installed in ```C:\Users\my_user\AppData\Local\Programs\Tesseract-OCR```, which was the default in the installer. When I try this in python: `image = Image.open(path); pytesseract.image_to_string(image)`, I keep getting the following issue:

tesseract.exe - System Error The code execution cannot proceed because libcurl.dll was not found. Reinstalling the program may fix this problem`

I've tried reinstalling the program to no avail. I also downloaded the libcurl.dll file from online (here and from dllme) and placed it the same directory as tesseract.exe. I also tried adding it to PATH, but still nothing works. Why doesn't this work after fresh installs? Thanks.

Hi,

First of all: make sure you have only one installation of tesseract (at least in the PATH)

Reason: I just installed  tesseract-ocr-w64-setup-5.4.0.20240606.exe and I run:

tesseract -v
tesseract v5.4.0.20240606
 leptonica-1.84.1
  libgif 5.2.1 : libjpeg 8d (libjpeg-turbo 3.0.1) : libpng 1.6.43 : libtiff 4.6.0 : zlib 1.3 : libwebp 1.4.0 : libopenjp2 2.5.2
 Found AVX2
 Found AVX
 Found FMA
 Found SSE4.1
 Found libarchive 3.7.4 zlib/1.3.1 liblzma/5.6.1 bz2lib/1.0.8 liblz4/1.9.4 libzstd/1.5.6

 => there is not support of curl otherwise there will  something like this:

tesseract 5.3.0-21-ge3fb
 leptonica-1.84.0 (Feb  7 2023, 16:46:21) [MSC v.1929 LIB Release x64]
  libgif 5.2.1 : libjpeg 6b (libjpeg-turbo 2.1.90) : libpng 1.6.37 : libtiff 4.4.0 : zlib 1.2.13.zlib-ng : libwebp 1.2.2 : libopenjp2 2.5.0
 Found AVX2
 Found AVX
 Found FMA
 Found SSE4.1
 Found OpenMP 200203
 Found libarchive 3.5.1 zlib/1.2.11 liblzma/5.2.4 bz2lib/1.0.6 libzstd/1.4.9
 Found libcurl/7.75.0 zlib/1.2.13.zlib-ng libssh2/1.10.1_DEV

I had a previous installation of "UB Mannheim" tesseract and it required libcurl-4.dll, so requirement of `libcurl.dll` indicates presence of another installation of tesseract, that was built in a different way...

Maybe using pytesseract.pytesseract.tesseract_cmd in your script can help (point to correct tesseract installation)
