Using Oracle Instant Client 64Bit with PL/SQL Developer 14.x 64Bit

Dear parallels friends,
I just test parallels with mac os big sur and its great so far.
My trouble starts with a connection to oracle databases using the latest Oracle instant client 64 bit from http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html and pl sql developer latest version from https://www.allroundautomations.com/products/pl-sql-developer/features/

PL/SQL Developer just telling me I have to make sure to have the 64 Bit version installed.
I extracte4d the client to C:\oracle\instantclient and set the pathes within pl sql developer accordingly.
On top of this I set the path variable.

Any idea what to check next?

Best,
Johannes
