Hello all,

I am getting “Can’t initialize OCI. Error -1” error when trying to connect in TOAD. I have TOAD 9.0.1.8, Oracle 10G R2 (32bit) and Windows 7 64 bit.

I have installed TOAD 10.6 and with the same result.

When i click on the error I get an “Access Violation at 008D3DFF in module TOAD.exe. Read of address 000000BC”. Below are the details from this error:

Hello all,

I have seem to resolve this issue by changing the UAC settings to "Never Notify". It requires a reboot and after that i was able to resolve this error.

Also, i am a local admin on the PC. I think you need both for this to work.
