As I mentioned in my initial question, I am installing OID 11g with sso 10.1.4.3.
I already installed OID 11g, that is why ODS schema already exists in database instance.
Repca 10.1.4.3 does not give the option to just install sso schemas. Repca 10.1.4.3 will try to install all schemas (sso, portal, disco, OID, etc.). The first thing repca do is to validate if already exists a metarepository in database instance. That's is why it detects that ODS schema already exists (11g installation) and show the warning that is going to delete it to create it again.
The directory error in wizard is because a
bug of the repca 10.1.4.3 installer, not because the directory does not have permisions or does not exists. That is why I use the
repca.jar file that comes in the patch p6681117_101203_MSVista.
This are the full screen shots:
