Re: Toad for Oracle 12.1 clashes with Oracle's 11g Forms Development Tools on Windows 7

Do you have multiple clients installed now? If so, change which home Toad uses on the login window so that you’re using the old one that worked. You can also make this the default home for Toad so it will use this home for new connections
instead of the true default which is the home listed first in PATH.

Thread created by Dan Marchant
We are upgrading our OS at work from Windows XP to Windows 7 (32-bit). Toad for Oracle 12.1 works just fine, until I install the 32-bit version of Oracle’s 11g middleware development tools (Forms and Reports Builders). The development tools work fine,
but Toad can’t connect to the database any more. The first time you try to connect, it gives the message “Can’t initialize OCI. Error -1”. Subsequent attempts give the message “OCI_INVALID_HANDLE”.

We have verified that everything we’re using is all 32-bit (OS, Toad, Oracle development tools, and Oracle Client), so there’s no 64-bit issues (unless Oracle’s development tools are slipping something in, but we specifically downloaded the 32-bit version).

Any thoughts? We need both of these tools available to us, and we’re getting pressure to figure this out soon. Most of the company, except for our development team, has already gone to Windows 7, but we can’t until all our toosl play nice together.

Thanks, Dan
