VB6 and Bartender

I am new to th forum and this is my first post. I have written a new VB6 program that uses Bartender to print law labels. I developed it on my PC Winows7 but when I try to run it from another PC I get a run time error (Automation Error). I called Bartender but they were no help. Anyone have any idea what I could try. I tried to be sure that all of the dll's were on the PC that doesn't work.
thanks
