First cancel login, enter pl/sql interface-Tools-Preferences

Secondly, you need to set environment variables (add an ORACLE_HOME and modify the path in the original path, this is not modified, mainly to let everyone know why to set environment variables)

These settings are good, you are logging in, the original error is estimated to be unable to resolve, now it may be unable to connect, haha, it should be plsql installation directory inside () such as C:\Program Files (x86)\plsql.

What you do is move this directory to a directory with no spaces, no (), no special characters, start plsql OK, definitely OK.

Get a computer, 64-bit will not be used, everywhere hit a wall, thank you for summing up, but also hope to help others.

Log in does not show an error directly blank, estimated not to be an administrator user (Administrator), try with administrator privileges.
