Instalando o Audiveris OCR para notação musical

Question

Estou tentando instalar o OCR Audiveris para notação musical. Como parte da instalação, instalei o ambiente Microsoft VC ++ conforme indicado nas instruções abaixo.

Minha pergunta é sobre a segunda parte das instruções: " A variável de ambiente do sistema TESSDATA_PREFIX deve ser configurada para / ocr / (incluindo o caracter final" / ") para que o software Tesseract possa recuperar seus próprios dados ."

Onde e como faço isso?

Obrigado.

Isto é retirado do site da Audiveris:

*   Microsoft VC++ 2008 to be installed beforehand (the free express edition is fine).
* The system environment variable TESSDATA_PREFIX to be set to <install-dir>/ocr/ (including the final "/" character) so that Tesseract software can retrieve its own data.
