java.lang.NullPointerException when installing Oracle XE 18c on Windows 10

Sam WheatApr 22 2021

I am trying to install Oracle XE 18c on Windows 10. I am not an Administrator however I run setup.exe as Administrator.
I received the error messages shown in the logs below. I've spent quite a bit of time with Google trying to fix this and have found these issues which appear to be similar but don't provide answers that work in my case.

I have also made the correction suggested here:

Thanks in advance for the assist.

Well of course the moment after I posted this I found this thread:
https://community.oracle.com/tech/developers/discussion/4271793/oracle-18c-express-edition-setup-rollback-during-installation#latest
which suggests removing the TNS_ADMIN variable which fixes the problem.
I checked the installation guide again here:
https://docs.oracle.com/en/database/oracle/oracle-database/18/xeinw/installing-oracle-database-xe.html#GUID-7BF9ACDC-1281-494C-AF96-77A25B1BD67D
A search for "tns_admin" returns no results. It is noteworthy that the documentation calls out ORACLE_HOME to be removed but omits TNS_ADMIN.
Also noteworthy is that there is a warning notice that says the page has been superseded by a newer release but clicking on the View Latest
link brings up a page for a completely different product.

From the installation guide:

1. Log on to Windows with Administrator privileges. (...)

2. If the ORACLE_HOME environment variable has been set, then delete it.

3. Download the Microsoft Windows version of Oracle Database XE.

I really feel like my time was wasted by a documentation omission that is known and should have been fixed. And really guys - is it that hard to add a line of code to the installer to check for the offending variable and report it to the user and terminate the installation? If you can't do that perhaps mention it in the log near the null reference ex? Just sayn.
