Emanager is intended to be backward compatible with older versions of CIX software, so you should not need Winadmin. I am sure that I tossed out those CDs a long time ago.

The only issues I have had I with eManager and very old version of CIX software, like 1.X. I don't know if UK versions are the same as US versions.

As far as the backup, if the system were to lose the programming in the processor (saved with the battery), then the system will pull the last saved backup on the media card (either SM or SD card, depending on the hardware). if there is no backup or no media card, then the system will boot to default settings.

You could backup the current configuration and factory default the system. I would consider using a media reader and saving the default.dat file before deleting it, just in case this is a good configuration
