I am trying to use the MainModule.StartReplacer macro in X7 but it is not doing anything?

We just moved our Graphic Designers from X5 to X7 and we use the StartReplacer macro alot. The problem is that, in X7 it does nothing. In X5, we would use it to pick a color to replace another color. This comes in pretty handy when you are making a file of 50 signs. Is there a trick to getting X7 to run the macro? I have tried it on 2 different PCs. We are running Windows 7 (some Windows 10) 64bit  and Corel X7 v17.1.0.572. Any assistance on this would be greatly appreciated.
