Oracle 19c installer froze/hangs -- datalog snippet attached -- can attach more

User_8PVIG

I've been trying to install Oracle 19c for a day now. Whenever I attempt to run the setup.exe file, after having extracted the original zip folder download, the setup.exe file does not finish executing and the installer freezes as shown in my attached snippet shown below.

When I hover over the installer, the mouse changes to the windows 'loading' circular icon, and no options are able to be clicked exit the exit button which brings about the datalogs.

The path for the db set up is 'C:\db_home'. When I run the setup.exe, I run it as an administrator. And yes, I am in an administrator account.

From the datalogs the only snippet that really sticks out to me is;

INFO: [Feb 27, 2021 5:03:27 AM] Checking whether the IP address of the localhost could be determined...

Please help

The inventory does not exist, but the location of the inventory is known: C:\Program Files\Oracle\Inventory

Looks as though there have been Oracle products installed on the machine before, and then the inventory files were deleted. Possibly someone trying to remove an Oracle installation. If you delete the registry key hkey_local_machine\software\oracle and remove any mentions of Oracle directories in environment variables and search path, you should be able to run the installer again.
