Hello all again, a new try. I am trying to install Oracle express 21c on a Windows 11 pro environment this time. That should be possible according to https://docs.oracle.com/en/database/oracle/oracle-database/21/ntcli/software-requirements.html
However, during installation I get an error message indicating to look in the cfgtoollogsdbca
[progressPage.flowWorker] [ 2024-07-12 15:00:17.716 CEST ] [InstallUtils.getOracleBase:489] OracleBase from orabase C:\app\vakan\product\21c

INFO: Log Directory :C:\app\vakan\product\21c\cfgtoollogs\dbca
Also looked in 21c\cfgtoollogs\dbca\XE where there is also a log file XE.log.
Here it states

Various adjustments done to XE_Database.dbc (21c\homes\OraDB21Home1\assistants\dbca\templates), step by step, but the error message keeps coming back
