Make sure you installed the right version and you're not trying to use a 32-bit version driver from a 64-bit application.

Can you "tnsping" your server?

It seems to be a client driver issue

Try to connect to Oracle DB through db tool like TOAD, SQL Developer etc then try to generate the db connection.

its a mismatch between the bits in the client and QV or vice versa

thanks for responses! How to find the oracle bit version from windows machine.

try this

select * from v$version

In the odbc manager application, when you click add, see the dll version if it says SQLORA32.dll then it is 32 bit

or alternatively you could read the documentation from the install folder

file:///C:/Oracle/product/10.1.0/Client_1/doc/install.101/b10131/pre_install.htm

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

i.e 64 bit it seems.
