I set this aside for a day and then looked at it again and found an article by you (@JohnDorlon) suggesting to do the following:
- Use the deinstaller to deinstall the 12.2 client
- Make sure there is no trace of any oracle client on your computer:
- Hard drive (check where it was installed, and also look under Program Files and Program Files (x86)
- System path
- Registry - specifically HKLM\SOFTWARE\ORACLE. If it's still there, delete that node after deinstall. Also HKLM\SOFTWARE\Wow6432Node\ORACLE.
- Environment Variables: Any oracle-related environment variables (except TNS_ADMIN) should be removed.
- Reboot
- Reinstall oracle client.
If you have 64 bit Toad, you must use 64 bit Oracle client.
If you have 32 bit Toad, you must use 32 bit Oracle client.
Once I did this, the correct Home directory and references showed up and TOAD is working now.
Thank you all for pointing me in the right direction.
