Window Builder FAILS TO INSTALL

[echavez-eb]

I tried to install Window builder from here:
https://download.eclipse.org/windowbuilder/latest/

I also tried installing by manually downloading the zip file. The "create new visual classes" button doesn't display.
I'm using Eclipse 2021-12

Here are the errors returned by eclipse when using the "install new software" option:

An error occurred while collecting items to be installed
session context was:(profile=C__Program Files_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Hi,

Can you please try using https://download.eclipse.org/windowbuilder/lastgoodbuild/ instead of https://download.eclipse.org/windowbuilder/latest/ ?

You could also try to download WB from eclipse marketplace. Therefor you open eclipse, go to "Help" then down to "Eclipse Marketplace". After klicking on eclipse marketplace a new window should open. Type WindowBuilder into the search field and then download the latest version of WindowBuilder.
I use the current Eclipse version 2021-12 (4.22.0) and WindowBuilder Nightly Build 1.9.8.pre
