title: Error performing OCR with Tesseract: read_params_file: Can't open deu
body: <p>While specifiing the language pack used to perform the OCR, i get the following error (for every language pack corresponding):</p>
  
  <pre><code>read_params_file: Can't open deu
  </code></pre>
  
  <p>I used the command as described in the wiki:</p>
  
  <pre><code>tesseract test.tif out -1 deu
  </code></pre>
  
  <p>The .traineddata files are located under tessdata and the TESSDATA_PREFIX is set to the parent directory of tessdata. The process works under default without given language information.</p>
  
  <p>I have Tesseract 3.05 installed on Windows 10.</p>
