Is there a way to change the method QTP 9.2 uses for text recognition

By default, QTP (QTP) 9.2 uses Windows API first, then OCR, for text recognition operations.
QTP 9.2 introduced a new text recognition mechanism. The information provided here applies to QTP 9.2 or higher. This solution is not available for earlier versions of QTP.
1. Open the registry editor. (Windows + Run -> regedit)
2. Navigate to HKEY_CURRENT_USER\SOFTWARE\Mercury Interactive\QTP\MicTest\OcrEngine.
3. Right-click on the mode value, and select "Modify."
4. Set the value data for the mode you want to use:

0 - No OCR. Instructs QTP to use only the Windows API-based mechanism (and not the OCR mechanism) to retrieve text from the object.
1 - Windows API/OCR. Instructs QTP to first try to retrieve text directly from the object using the Windows API-based mechanism. If no text can be retrieved, QTP tries to retrieve text using the OCR mechanism. (Default) (Highly recommended when working with CJK languages.)
2 - OCR/Windows API. Instructs QTP to first try to retrieve text from the object using the OCR mechanism. If no text can be retrieved, then QTP uses its Windows API-based mechanism to retrieve text from the object.
3 - OCR only. Instructs QTP to use only the OCR mechanism (and not the Windows API-based mechanism) to retrieve text from the object. (Required when working with Windows Vista.)

6. Restart QTP.
