Indexer doesn't run in eclipse IDE ?

Eclipse IDE for C/C++ Developers
Version: Neon.1a Release (4.6.1)
Build id: 2016 1007-1200
From main menu, I go to Window - Preferences - Indexer but Indexer doesn't run ?
I need to run Indexer so I can navigate my source code.
I right clicked on my project and selected properties. But there is no C/C++ General - Path and Symbols. Why ?
Is it because I downloaded this large 'C' language project through eclipse subversion plugin ? I didn't manually create this project in eclipse.

Did you try these steps?

Thank you for the reply.
My indexer isn't even running.
When I right-click on my project, I don't have Index menu.
From Windows - Preferences - C/C++ - Indexer, I cannot run the indexer. I click OK or Apply but Indexer doesn't run.

Are you sure indexer is enabled (the link shows how to do this)??

Yes, the indexer is enabled. Please see attached.Indexer Enabled

Can't help you unless you show the entire preferences pane for the indexer...

Attached is entire preferences page. Thank you!Indexer Preferences Page
