How to get mrr file to work in ProjectWise Explorer Client CE


i created a simple mrr file with ProjectWise Menu Editor as you can see in the following image.

What i don't know is simply how to get it work in ProjectWise Explorer Client? I copied the mrr file into the x86 and x64 bin folders of ProjectWise but no luck. Because the function i like to use are standard ProjectWise document functions do i need to specify a dll or something else?

Thanks for you help!
