I have PM and I'm trialing PM+.
I copied BrowsewithPMService (dated 11/1/18) from the PM+ disk image to the /library/services/ folder as per instructions.
However, every time I try to use it, it tries to launch PM -- not PM+ as desired. The error box comes up the the PM logo (yellow iris) vs. the PM+ logo (green iris). The error is: "Another instance of Photo Mechanic is already running. This instance will now terminate. Please quit the other instance and launch this one again."
Do I need to delete the PM install to run PM+?
Oh, and separate, but FYI, I get the trial date countdown message box when I open PM - that shouldn't happen.
