Hello everyone,

So a while ago I installed the 19c database. But for some reason I deleted it. And when I try to download it again its showing me a configuration assistant failed error. When I deleted it, I deleted everything, the environment variables, the groups and the registries and I cleared temp and the recycling bin. I dont know why this is happening.. I need to download fast so I can work on my university project.

It shows a fatal error in the logs: [FATAL] ORA-12560: TNS:protocol adapter error.

Hope someone helps Been trying to solve this for a week and nothing on google helps..
