When using RTUtil (v 18.104.22.168) on my Windows 7 machine, whenever I open an existing (and valid) .RTU file, or extract a project from configuration file, the file will load but will not show anything under the Network, Hardware or Signal Trees. It looks as if the file is empty and unconfigured.
If I follow the exact same process with the same files on a Windows 10 machine (same version of RTUtil) it all loads correctly and displays all the information.
A I missing a step when opening these files? Do I need to do something else to make it work? Or is there perhaps a bug?
