py2exe generated .exe shows error message on windows systems

I have developed a python openCV based OCR system and generated an .exe file using py2exe. The problem is it shows an error message on several Windows systems.

Error message:

Exception in Tkinter callback Traceback <most recent call last>: File "Tkinter.pyc", line 1536, in __call__ File "gui_tes3.py", line 89, in VerifyDocument File "gui_test3.py", line 37, in OCR File "pytesseractpytesseract.pyc", line 94, in run_tesseract File "pytesseractpytesseract.pyc", line 161, in image_to_string File "subprocess.pyc", line 710, in __init__ File "subprocess.pyc", line 958, in _execute_child WindowsError: [Error 2] The system cannot find the file specified

Any kind of help will be highly appreciated....... Thanks in advance...
