Java/Tesseract-OCR: Unsatisfied LinkError libtesseract302

I'm migrating a coworkers Tesseract-OCR application from MacOSX to Windows 64 and running into issues with library paths.

When I execute an OCR process, I get this:

Caused by: java.lang.UnsatisfiedLinkError: Unable to load library 'libtesseract3
02': The specified module could not be found.

I have Tesseract 3.02.02 installed via the Windows installer: https://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-setup-3.02.02.exe&can=2&q=

I searched the installation folder and only found a libtesseract302.rc file sitting in the following path, and I don't think it's the right file anyway. 

C:\Program Files (x86)\Tesseract-OCR\tesseract-ocr\vs2008\libtesseract

System env variables:

TESSDATA_PREFIX = C:\Program Files (x86)\Tesseract-OCR\

What am I missing?

I believe that setup installer only includes the .exe, data, and others but not the .dll that your program needs. You will need to download the source and build it with the appropriate configuration. And since Tesseract is a 32-bit library, it will only work with Java 32-bit.
