Thanks, Zdenko. I didn't actually break the installation, I only wanted to install it to subdirectory c:\tesseract\tesseract-ocr rather than in Program Files. The way I now understand it is that a new instance of the Dos Window (command) must be raised to refresh the environment after making changes to it. I looked in control panel and saw that there were different PATH's for user and for system. Just by closing that black window and running command.com (on win2000) again, the environment was fixed. Basic, I know, but I had forgotten that. Now Set command shows: TESSDATA_PREFIX=C:\tesseract\Tesseract-OCR\ My problem, as usual, was trying to do too many things at once. I thought maybe I needed ver. 3.00.1, which I downloaded and copied the new tesseract.exe over the old one, didn't uninstall ver 2.04, etc., etc. Seems to work now.
