"Unknown User" error while logging into ION Setup 3.0.
The customer has an older version of ION Setup already installed on the machine and the two versions are conflicting.
Make a backup of the IONSetup.dat file in the Program Files\Schneider Electric\ION Setup folder. This file can
be copied back into the folder afterwards to retain all setup/meter information added in ION Setup.
Uninstall all versions of ION Setup, restart the computer and then re-install the newest version as an administrator on the computer.
