Step 1. Copy the dll and ocx files to windows system directory.
Windows 32-bit: copy "pdftoimage.dll & pdftoimage.ocx" to C:\Windows\System32
Windows 64-bit: copy "pdftoimage.dll & pdftoimage.ocx" to C:\Windows\SysWOW64
Step 2.Register the component ocx in your system using the regsvr32 program that is provided with the windows operating system.
Windows 32-bit: regsvr32.exe pdftoimage.ocx
Windows 64-bit: c:\windows\syswow64\regsvr32.exe pdftoimage.ocx
