In the Start menu, there is Symantec Endpoint Protection.But sub-menu is empty. Any possible cause?

You can remove the folder and registry from the system and try to reinstall.

share the sep_insta.log for the failure.

What is showing on SEP_INST.log, please post the log.

Run a clean wipe and do the installation again.

Thank you for posting in Symantec community.

I would be glad to answer your query.

SEP is not installed completely.

Have you tried to repair the corrupt install by running the setup again?

You should refer the following article if repaired rolls back.

Please let us know on what OS you are trying to install SEP on?

Please upload us the SEP_Inst.log and SIS.inst.log from %temp%.

These logs would provide us the root cause of the issue.

In case, it is a Windows 8 machine, check this Article:

Troubleshooting for failed install of SEP 12.1 RU2 client on Windows 8 (Win8)

Hope that helps!!

Can you verify in the install log that the install was successful?  If not, try running the newest version of CleanWipe to remove all existing installs of SEP and then reinstall.

The installation was not complete.

If the installtion rollsback during reinstallation try the following.

Run the latest cleanwipe tool

Dlete any existing symantec endpoint protection folders from the installation directory C:\Program Files\Symantec, C:\document&settings\all users\application data\symantec and also from C:\Program Files\Common Files\Symantec Shared (delete the symantec folders)

backup your registry and delete any entries of symantec endpoint protection in the registry ,and reboot your system

and try installing the SEP again.
