64 bit support in the IDE?

[sse]

Is there 64 bit support in the IDE? if so how to make a single delphi proj, targeting both 32 and 64 bit, but that can display data in the IDE?

I have 64 bit oracle client installed and would like to create a 64 bit Delphi App. using Delphi Tokyo.

When I try to connect a TOracleSession to a LogonDatabase I immediately get a message saying make sure to have the 32 bit client installed, even though the Build is targeting 64 bit Windows. At this point I am not trying to target 32 bit, but will eventually. I understand I will need two Oracle_Homes.

---UPDATE---

Ok, I was able to preview the list of db's in the IDE, but had to install 32 bit client, even when it wasn't needed for a 64 bit. I am guessing the IDE must use OCI client in 32 bit oracle folder

---Feel free to delete this post... I could not. ---

Thank you

I have a perhaps related error - see my post at:https://forums.allroundautomations.com/ubb/ubbthreads.php?ubb=showflat&Number=57488#Post57488

It's just the other way round: compiling 64bit works, compiling 32 bit does not work, and design time access (32bit) does not work too.
Both oracle clients (32bit and 64bit) are installed ...

The RAD Studio IDE is 32 bit, so all design-time components are also 32 bit. Consequently you need a 32 bit Oracle Client for design-time connections to Oracle.
