Well, to be able to do anything with CR in VB 6 you need the Developer SKU. And unfortunately, 8.5 is so old I doubt you will be able to obtain it. However, I may be wrong so giving sales a dingle and asking will not hurt: 866-681-3435
Referencing craxdrt and craxdui without the rest of the runtime is futile also.
I understand your annoyance and frustration, but you are not working with the correct product installs. It's kind of like trying to start a car - you have a key, but it's from a different car so it does not quite fit.
