What steps will reproduce the problem?

I think it's the file separator issue, how can i do with it ?

I gues you install tesseract by installer et least 2 time to different 
location. You need to manually change settings (windows XP): click on "My 
computer" -> Properties -> Advanced -> Enviroment Variables: In block "User 
variables for..." look for item "TESSDATA_PREFIX", double click on it and to 
"Variable value" put your location of tesseract tessdata ("D:\Program 
Files\Tesseract-OCR\" OR "E:\Program Files\Tesseract-OCR\").

Or wait for new new installer for 3.01 ;-). Anyway you will need to first 
install it than to uninstall it (this should clear your registry correctly) and 
to install it once again.

Thanks for your advice,but I think it's not the TESSDATA_PREFIX problem, It's 
the file separator,you see my attach, tesseract read the file in 
"E:\Tesseract-OCRtessdata/eng.traineddata", not 
"E:\Tesseract-OCRtessdata\eng.traineddata", why did it
use linux separator in windows?
I remove the duplicate TESSDATA_PREFIX，and now the result is in attach.

Now, the path appears to miss the slash in front of tessdata.

@wangjava:
"\" is escape character only windows use it as directory separator ;-)
You HAVE problem with TESSDATA_PREFIX ;-). 
"E:\Tesseract-OCRtessdata\eng.traineddata" do not exists on you system. Try it.

BTW: there is also 3.01 installer...
