Oracle 12 client 64x 32x installed - Oracle Home not detected

I’ve installed Oracle 12 client 64 and 32 bit on my machine and Toad 64bit is only available to me.

I understand that 64bit Toad is only compatible with 64bit Oracle client.

What I don’t understand is why Toad is not recognizing the 64bit client.

Here’s what I’ve done:
Installed Oracle 12 64x client
Toad is OK. Able to connect to a database.
Installed Oracle 12 32x while still having 64x
Toad does not see the 64x Oracle client


Your Oracle-Client\bin directory seems not to be in PATH variable.
