KB37622: "The name is already used for a subkey or named value" error message appears when registering an existing system in MicroStrategy Narrowcast Administrator

SYMPTOM:
When attempting to register an existing system using Strategy Narrowcast Administrator the following error may occur and prevent the system from being registered.

The name is already used for a subkey or named value.

This is because this option switches the location of the registry entry from HKEY_CURRENT_USER to HKEY_LOCAL_MACHINE.
 
ACTION:
To resolve this issue follow the steps below:

1. Switch the "Registering Systems" checkbox such that all the systems registered are visible.
2. Go to System > <System Name> > Edit System Configuration > Clustering.
3. Select the option "Remove all machines from the Narrowcast Server system."
4. Go to System > <System Name> > Unregister system.
5. Switch the "Registering Systems" option back and register the new system.
