Hey,
It could be that your delivery center server is not running with the bundled JRE, to explicitly set that you can modify the deliveryCenterServer.ini and before the -vmargs add:
-vm
C:\SDC\Server\server\jre\bin\javaw.exe
Just check that this file exist, other things to check are. Are you running with an antivirus? Is the windows defender running? If any of these is true could be that it removed some files from the install directory?
Best Regards
