This message means that the ENS is not in good state. This either due to 3rd party dll hooking or the point product has been corrupted.
Run the ENSRepairCacheutilities against all impacted modules and then restart the system. The repair installation tools are silent, and must be run one after another. To determine whether a repair installation tool has completed, check the MSI task in Task Manager.
Open an administrator command prompt.
Execute the following commands one at a time. Allow each MSI installer to complete before proceeding to the next command. The /famus switches run a repair action while forcing the rewriting of all ENS files and registry entries to resolve any potential corruption sources.
