The Enterprise Server Edition is unable to run a backup or start the service.
The Enterprise Server Edition (ESE) uses a different file location to the Server Edition (SE). Whilst SE stores cache, database and "toBackup" files in sub-folders of the installation folder i.e. "C:\Program Files\Attix5 Pro\Backup Client SE", the ESE stores its local files separately in "C:\ProgramData\Attix5 Pro\Backup Client ESE". The files are organised differently in ESE, so only one path is specified.
The data path can be changed within the ESE client GUI, but this may not always be possible. For example, if you run out of space on the C drive, the ESE client service will be unable to start, preventing you from changing the setting.
