  1. Make sure you have the right bit (32/64) Oracle client installed. It should match Toad.

  2. Sometimes this error will occur if you make a connection in Toad using one Oracle client, then you disconnect and try to make a connection using a different Oracle client. Unfortunately, the DLL’s don’t always unload properly and it can cause errors.

64 bit Windows likes to install 32 bit programs in a “Program Files (x86)” folder. Having a parenthesis in Toad’s path will cause the older Oracle clients (most versions 10.2 and older) to fail to connect. This is an Oracle bug and it was fixed in version 11. To work around it, re-install Toad to a folder without parenthesis (or get a newer Oracle client!)
