Typically, what this means is that you are trying to install a Windows program onto the Pocket PC. While the Pocket PC is technically running Windows (Windows Mobile), it's not the same as your PC, and does not recognize programs that your PC will recognize, and vice versa.
Whatever program you're attempting to run on the Pocket PC needs to be run on your regular PC, with the Pocket PC connected. Epocrates must install from the "real" PC, which will in turn install to the Pocket PC through ActiveSync.
If this still doesn't work, ensure you've downloaded the correct file (make sure it's for Pocket PC and not Palm), and try again via the PC. Hope it works for you.
