Here are the steps: (per Jeff)
if you get class not registered error you need to register the DLL file. go to start>run>
then type in regsvr32
then find the tbarcode2.ocx and drag it into the run box.
it will then give you regscr32 c:retailrprotbarcode2.ocx
you also need to register the tbarcode3.ocx file
find the tbarcode3.ocx and drag it into the run box.
it will then give you regscr32 c:retailrprotbarcode3.ocx
it will say it is registered then it will work.
