i have an ultrabook with WIndows8.1 64bits
I have installed and uninstalled oracle11g, oracle12c 32bits and 64 bits
when i install oracle xe 11g 32bits, i can connect with sqlplus but i cannot connect with oledb
when i try to connect to oledb, i have the error "provider is no longer available. Ensure that the provider is installed properly."
I do not really understand, why it does not work, because normally oledb is installed with the installation of oracle.
I have done multiple search in google, and it seems that i should install ODAC
