Eclipse Installs for nonexistent user

Issue

Some time ago my company migrated our Windows profiles and created new ones. I had an old installation of Eclipse Neon on the old profile.

I'm now trying to install a fresh copy of the latest eclipse and it always fails because it's trying to create folders for the old Windows profile, that doesn't exist.

Here's one of the errors it reports:

ERROR: org.eclipse.equinox.p2.artifact.repository code=1003 Unable to write to repository: file:/C:/Users/oldUser/.p2/pool.
    java.io.IOException: Failed to create directory C:\Users\oldUser\.p2\pool\plugins.

        at org.eclipse.core.internal.jobs.Worker.run(Worker.java:63)

The folder C:\Users\oldUser does not exist anymore. Why isn't the installer installing it for the user I'm actually logged in as?

As far as I can tell, none of the old Eclipse Neon stuff still exists.

Solution

Turns out it had to do with a feature called "Bundle Pools". The installer, by default, has this feature turned on - it somehow knew / remembered the previous Neon installation and was trying to write to that. Turning off the "Bundle Pools" feature during the install allowed the setup to finish.
