DOA 4.1.3.5 component with OCI Error

[Berni]

Running Delphi XE4 with DOA 4.1.3.5 on Windows 10 with installed Oracle client_32 and client_64 results in an error at design time:

Could not initialize "C:\Oracle\product.1\client_32\bin\oci.dll"
Make sure you habe the 32 bits Oracle CLient installed.
OracleHomeKey: SOFTWARE\ORACLE\KEY_OraHome32
OracleHomeDir: C:\C:\Oracle\product.1\client_32
Found: oci.dll
Using: C:\Oracle\product.1\client_32\bin\oci.dll
LoadLibrary(C:\Oracle\product.1\client_32\bin\oci.dll) returned 0.

Design time access to the component setting, for example LogonDatabase results in the error above.

Compiling the programm as 64bit and running it => works.
Compiling the programm as 32bit and running it => fails.
Component access at design time results in the error above.

Any hints how to solve this design time problem?

Can you start C:\Oracle\product\12.1\client_32\bin\sqlplus.exe to check if the 32 bit client works correctly?

Hello,
thanks for the Tip: sqlplus.exe in win_32 says "Zugriffsfehler".
sqlplus.exe in win_64 is running.
I am checking the installation, there must be something wrong.
