I'm trying to install XE 18c on a fresh Windows 10Pro x64 machine. I deleted the CDB because I want to run a "regular" non CDB DB on this system. After I set my options and click Finish after a couple of seconds I get:
I click ok and the installer just quits.
I have an admin account and ran DBCA as an admin just to be safe after it failed the 1st time. Same result.
