I have installed Toad 9.7 on Windows Sever 2008 Enterprise x64 machine where I also have Oracle 11gR2 X64(Oracle Server & Client) editions installed.
I have both Oracle Server and Client installed into diff folders under C:\app\Administrator.
Initially I have installed Toad 9.7 into c:\programfies x86 folder and I go the error "You don't have Oracle Client installed" at Toad startup
I have tried reinstalling Toad 9.7 to custom folder assuming that the folder programfies x86 is giving the problem but I am getting the same error though I have Oracle Client installed into diff. folder
