I was just wondering do i need to install the full client again, just to have the odbc datasoruce administator install the oracle driver, so it can sucessfully connect to
existing oracle database?
No - you can use the Instant Client instead if you want.
See the instant Client download page
You need the Instant Client Package (Basic or Lite) and the additional ODBC package as listed. There are other optional packages you might want such as the one for SQL*Plus.
Sorry for not providing enough information. I finally managed to download and extract the 64 bit version of the client instantclient-basic-windows.x64-220.127.116.11.0
Now i am having issues installing it. I read the documentation. It only mentions changing my Path variable to where the client instant is installed
I am really only inerested in having the ODBC Connector to have the correct oracle driver installed as explained earlier
In the instantclient-basic-windows.x64-18.104.22.168.0, there is no setup file or install file
