Hi,
I have installed TOAD v13.0 and Oracle client 8i on my Windows 10 OS. I could see SQLPLUS is working. But when I open TOAD, I'm getting error like No valid client found. Can someone please help here.
Is there a reason why you are using such an old client?
If you need to connect to old database versions, you should be able to do that with a 10gR2 client
