installation of R12.2 on Windows fails at adrunfmw.cmd due to thread count

Hello,

I am trying to install EBS 12.2 on Windows Server 2019 (data centre edition) using RapidWiz.

The installer hangs at 29% when it is running adrunfmw.cmd

Digging into the logfiles I see this error:

Executing command: c:\StageR22\startCD\Disk1\rapidwiz\jre\NT\1.6.0\bin\java -mx600M -classpath .;c:\StageR22\startCD\Disk1\rapidwiz\jlib\java;c:\StageR22\startCD\Disk1\rapidwiz\jlib\xmlparserv2.jar;c:\StageR22\startCD\Disk1\rapidwiz\jlib\ojdbc14.jar;c:\StageR22\startCD\Disk1\rapidwiz\jlib\oui\OraInstaller.jar;c:\StageR22\startCD\Disk1\rapidwiz\jlib\oui\ewt3.jar;c:\StageR22\startCD\Disk1\rapidwiz\jlib\oui\share.jar;c:\StageR22\startCD\Disk1\rapidwiz\jlib\oui\srvm.jar
