Rob,
You should first of all reset to factory the AP, Push the reset button for more than 15 seconds, do it twice, after this you can enter with the default credentials
username: super
password: sp-admin
If you downloaded a zip file from support site for example:
ZoneFlex Solo Access Point 104.0.0.0.1347 (GA) Software Release
Unzip it, this file contains all the bl7 files for each Ap supported, after that choose the .bl7 file corresponding to 7372 ZF Access Point, in the upgrade tab select the local upgrade, in this case is the file named ZF7372_104.0.0.0.1347.bl7 and upload it, after this perform the upgrade
After this process you will be able to manage all the configuration as a standalone device
Regards,
