Google Earth installer does not create the proper registry classes in 64-bit machines, thus preventing the communication with other programs.
To run the Plex.Mark! software in a 64-bit computer you should download and apply the patch we have created to correct the missing registry entries. Download it from here.
Contact us to send you the required patch at email@example.com
You should also copy the entire "Plexscape" folder from the "C:\Program Files (x86)\Common Files" to the "C:\Program Files\Common Files" directory.
Soon will be available an updated installer of Plex.Mark! in order to automatically resolve the issue.
