Getting "You have no Oracle clients installed" error message when connecting or launching / starting Toad for Oracle version11.6
- There is no Oracle client installed on the machine
- The Oracle client installed is 64-bit when you have a 32-bit Toad version 11.6 installed or vice versa.
- Environment Variable Path is missing.
RESOLUTION 1:
Check to make sure there is an Oracle client installed on your machine. If there is not, you will need to install one.
RESOLUTION 2:
If there is an Oracle client installed on the machine, check to see if it is 64-bit or 32-bit. The Toad installer in version 11.6 must match that of the Oracle client (32-bit or 64-bit).
RESOLUTION 3:
1) Look for your OCI.DLL file in your computer and Copy the location path i.e. C:\oracle\product\10.2.0\client_1\BIN
2) Right-Click your My Computer | Properties | Advanced Tab | Environment Variables button
3) Under ‘System Variables’ at lower half of screen, highlight ‘Path’ | click Edit
4) Under ‘Variable Value:’ | go to the very beginning of the existing entry | Paste the path you copied earlier
5) Add a semi-colon (;) | and then click OK, OK, OK.
6) Start Toad and re-test
