• ltthunkserver.exe (this must be registered)

• ltthunkutlu.dll

• Ltthunkutlx.dll (used only in 64-bit environment)

• ltdocthunku.dll

• ltdocthunk2u.dll

To register the THUNK:

• Go to Windows Command prompt.

• Write the following line:
  C:\Program Files\LEAD Technologies\LEADTOOLS 16\Bin\Common\OCR Thunk\ltthunkserver.exe" /regserver
