TOAD (15.1) not recognizing TNS_ADMIN env variable

I previously set a TNS_ADMIN variable at the user level and TOAD would not recognize it. I tried to set one at the system level, and TOAD still does not see it. How can I fix this? Thanks.

Make sure your Oracle client is listed in your PATH. You want to add the folder containing oci.dll. TNS_ADMIN simply points to where your Oracle net configuration files exist. The Oracle client still needs to be properly configured by being in PATH, etc.

Also, for whatever reason, you need to restart your PC for Toad to find something after adding it to your path.

Thanks all, added to my PATH, but I'll need to wait until EOD to reboot.

You should be able to run Toad in no-client mode until then. No reboot is needed for environment variable changes.
