I want to upgrade the SAP NetWeaver Application Server Java from Stack 15 to 19.
In the installation phase 'Check prerequisites' I get this error:
ERROR 2007-01-29 14:43:38 FKD-00070 Error when opening table container file C:/Program Files/sapinst_instdir/PATCH/PRC/keydb.xml for writing. Possible reason: "read-only"
The strange thing is that the read-only box is not marked, also not for the folder PRC or the whole sapinst_instdir.
And I have administrator rights.
I also rebooted the computer and deleted all content in sapinst_instdir and started new. But the error still occurs.
Does somebody have an idea what's going wrong?
Thanks in advance,
