Installation of the Symantec Endpoint Protection Manager (SEPM) fails. Attempting installing to another drive or partition does not resolve the issue. Using the Cleanwipe tool and then attempting the reinstall is likewise unsuccessful.
At the end of the Symantec Endpoint Protection Manager installation a rollback is performed.
An example from the SEPM_INST.log:
Running the SymHelp tool to check for potential installation issues can often reveal the cause of the failure.
SEPM installation failures have been known to stem from a corrupted Windows Script Environment or from conflicts with previous installations of LiveUpdate. However, these are not the only causes.
Reinstall Windows Script Environment
Install the Symantec Endpoint Protection Manager, using either the latest available LiveUpdate client software or the exact version that shipped with SEP. LiveUpdate client software can be downloaded from the articles referenced below.
Make sure UAC is not enabled in the registry (Source: https://gallery.technet.microsoft.com/Registry-Key-to-Disable-UAC-45d0df25).
