Server Administrator forgot / lost APC PowerChute password and can no longer access UPS software.
The only way I found to reset APC PoweChute password is to uninstall and reinstall PowerChute Server and Agent modules. During installation you'll be asked to create a new username and password. There is no need to reinstall Console. All three modules can be installed using the same installer (it gives you an option to choose which modules to install).
