EM patch 13.4.0.5 error on create property file (createkeys)

I'm installing EM patch 13.4.0.5 on windows 2019. I did a simple installation. Assuming the weblogic admin user is "weblogic" and password is what was entered for the "Administrator Password" during installation. However it fails to create the property file:

\> set ORACLE_HOME=D:\OEMMiddle

\> set PATH=%ORACLE_HOME%\bin;%ORACLE_HOME%\OMSPatcher;%PATH%

\> echo %PATH%

\> cd /d %ORACLE_HOME%

\> mkdir KEYS

\OEMMiddle>omspatcher\wlskeys\createkeys.cmd -oh \OEMMiddle -location \OEMMiddle\KEYS

Please enter weblogic admin server username : weblogic

Please enter weblogic admin server password : **************
