Toad for Oracle 11.0 R2 Installation Failure

Hi Everyone,

I am struggling with the Toad installation on my laptop after formatting my hard drive. This is the first time I encounter this problem after many years of installation. The same version is working as before except the Oracle version is different and Windows sign-on as local administrator.

Version: Toad for Oracle 11.0 R2 Commercial (* Run as local build-in administrator)

OS: Windows 8.1 x64

Oracle Version:

I checked the below log and it stated the error "Toad for Oracle 11 -- Error 1406.Could not write value to key \SOFTWARE. System error . Verify that you have sufficient access to that key, or contact your support personnel."

I have verified the windows registry and the folder and sub folders have administrator full rights. I even added "everyone" for the folder permission.


Has anyone encounter such issue with Toad installation.

Many thanks.

Hi, Nope, none of the tips from google help. I think I will format again and install Toad in the first place. Give up! Thanks anyway.
