I saw an Oracle video tutorial.
And I followed the course and installed it.
***Moderator action (Timo): removed the link to the video, as it could be spam.***
1. I installed oracle 11g and confirmed that it runs normally on the cmd screen.
2. However, it has not been run in the Oracle SQL Developer installation course.
(Same error message as the title)
I did not know the cause.
So I reinstalled Oracle Database 11g and I turned off the HR account in [Password Management] and gave it a simple password.
However, Oracle SQL Developer still displays a red character.
So I typed cmd as I was told in Googleing, and it is 'ready'.

Again, when I saw the video course,
I clicked 'services.msc' in 'windows search' and compared it with the lecturer. My file was different.
Something seems to be wrong with the installation,
but Oracle was not in the Windows Control Panel and I could not erase Oracle.
So I wanted to put the whole Oracle folder in the trash and install it again.
However, people have warned me that if you accidentally delete the Oracle folder, there will be a disaster.
So I did not delete it.
I installed it again instead.
But it has not been solved.
What should I do?
