I have put a new picture. And new information from support:
Article ID in Vontu knowledge base: 54492
Solution: kill process sqlplus after click "next" in setup.
New error:
The installer has detected that the Oracle database is configured to use an incorrect character set: CL8ISO8859P5
Symantec DLP requires the Oracle database to use the "AL32UTF8" character set
But we can not change character set...
Someone solved this problem?
