[INS-20802] Oracle Database Configuration Assistant failed

2. Error cause

3. Solution

Please help me. This error is always reported when ORACLE is installed.

The best way is to follow this process,
1. Delete oracle. There are many terms on how to delete it on the Internet (step by step ).
2. restart the computer.
Third, install 360 security guard. The Registry may not be deleted. Optimization and garbage removal. (Dummies are still a little useful .)
4. Uninstall the 360 security guard because it often changes the oracle registry.
Fifth, oracle Installation will not cause problems ......
I hope you can follow this operation. This is also my failure experience, just like you. I declare that I am not responsible for 360 reputational losses.
