Hello,
You need to first uninstall Adaxes 2012.1 Administration Console, and only after that install the 2013.1 Administration Console.
Command line for silent installation of Adaxes Administration Console:
msiexec /quiet /i "<adaxes_msi_full_path>" ADDLOCAL=AdminConsoleFeature
where <adaxes_msi_full_path> is the full path to Adaxes installation package, for example, C:\adaxes_x64_en.msi.
