I downloaded ODAC122010Xcopy_x64.zip from https://www.oracle.com/database/technologies/odac-downloads.html and installed it.
install.bat oledb c:\oracle myhome true
And created an entry in c:\oracle\network\admin\tnsnames.ora.
Then I launched "Sql Server Import and Export Wizard", selected the data source of "Microsoft OLE DB Provider for Oracle", clicked "Properties...", filled the information and clicked "Test connection". However, it got the following error?
