This problem occurs when you install the higher version of oracle client and the Toad version may not have the support or if you have installed the 64bit Oracle client and the toad version is 32 bit.

please confirm the above since you have not given any version details.

sometimes if there is multiple oracle homes installed the problem arise. please check and configure toad with the latest one.

Also check which is the current path in environment variable.

Right, so the issue is obviously with versions since you have 2008 R2 64, better you download the newer version of Toad as follow which is V.11

This is clearly the version issues, as toad is only 32 bit compatible software.

you can install a 32 bit oracle client then try to access through toad.
