Missing Web Tools on Eclipse for Java [message #1797740]

I'm working on some java project on Eclipse IDE for Java Developers, version Photon (4.8.0).

Now I need to develop some web page (html, css and javascript).
So I have installed:
- Eclipse Java EE Developer Tools 3.10
- Eclipse Web Developer Tools 3.10
- HTML Editor (WTP)
I restarted Eclipse more than once.
Installation was OK: the extensions appear correctly in Eclipse Marketplace > Installed tab.

But... there is no trace at all of Web Tools in Eclipse.
I looked everywhere:
File > New...
Window > Perspective
Open With...
All the menus are identical as before, simply java oriented.

How can I "activate" the Web Tools?

Check whether a Capabilities preference page exists and has options you need to enable.

Thank you for the suggestion.
Unfortunately in Window > Preferences > General there is no Capabilities page...
Maybe because I have installed Eclipse Platform instead of Eclipse SDK ?

That could be.

Following this answer, I installed Eclipse Platform SDK as plugin, but nothing changed in Eclipse: still no Capabilities page, same java menus...
Is there something else I could do to activate Web Tools?

Supposing that Eclipse Platform SDK was not what I needed, I reverted to previous installation: Help > About Eclipse IDE > Installation Details > Installation History.
Then from Help > Install New Software... > http://download.eclipse.org/eclipse/updates/4.8 I installed Eclipse SDK (org.eclipse.sdk.ide) that includes also Eclipse Project SDK (org.eclipse.sdk.feature.group).
Restarted the program and... nothing changed in this immutable java oriented Eclipse.

What else could I do?

Is there a feature named "Eclipse Project SDK" that you can install? Alternately/preferably, does updating to 2018-09 help?

As I wrote before, I have already installed "Eclipse Project SDK" (included in "Eclipse SDK"), and nothing was changed.

About updating to Eclipse 4.9 (2018-09), the process stops with this message:

The Program Files directory often causes permission problems with Eclipse. It might be preventing something from being updated that needs to be updated. Maybe unpack the 2018-09 Java IDE somewhere else altogether and then install the web tools?

I really don't think it's a permission problem of Program Files directory, rather a problem of files not found in remote repositories.
I opened Window > Preferences > Install/Update > Available Software Sites, and I added & removed some repository location...
Now after Check for Updates the error is:
Problem Occurred

An error occurred while collecting items to be installed
session context was:(profile=C__Program Files_Eclipse_java-photon_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
No repository found containing: osgi.bundle,org.eclipse.nebula.widgets.tablecombo,1.2.0.201810302204

So I added the repository http://download.eclipse.org/nebula/releases/1.2.0, but the error is still the same.
