ActiveX component can't create object

Hi,
I try to load a program called Otrader and it loads up but gives an error message 429 which is ActiveX component can't create object. It then closes the program down.
I installed it on another computer, same OS but it works on that one.
What can cause this error. I think i may have already reinstalled activex components from downloading so please suggest as many solutions as you can think of.

THanks
