I am new to nifi trying to install it but when I run command nifi.cmd start I get this:

JAVA_HOME=C:\Program Files\Java\jdk-21 NIFI_HOME=C:\nifi-2.7.2-bin\nifi-2.7.2

but it doesn't write that "nifi has started" when I checked the log file it has the following:

nar\extensions\nifi-server-nar-2.7.2.nar-unpacked\NAR-INF\bundled-dependencies\nifi-ui-2.7.2.war] Context Path [/nifi] 2026-01-17 19:26:53,803 INFO [main] org.apache.nifi.web.server.JettyServer Loading WAR [C:\nifi-2.7.2-bin\nifi-2.7.2\.\work\nar\extensions\nifi-server-nar-2.7.2.nar-unpacked\NAR-INF\bundled-dependencies\nifi-web-api-2.7.2.war] Context Path [/nifi-api] 2026-01-17 19:26:53,810 INFO [main] org.apache.nifi.web.server.JettyServer Loading Docs [C:\nifi-2.7.2-bin\nifi-2.7.2\docs] Context Path [/nifi-api] 2026-01-17 19:26:53,813 ERROR [main] org.apache.nifi.runtime.Application Start Server failed java.lang.IllegalStateException: Management Server Address System Property [org.apache.nifi.management.server.address] not valid [127.0.0.1:?????] at org.apache.nifi.runtime.ManagementServerProvider.getManagementServer(ManagementServerProvider.java:51) at org.apache.nifi.runtime.Application.startServer(Application.java:128) at org.apache.nifi.runtime.Application.run(Application.java:78) at org.apache.nifi.runtime.Application.run(Application.java:60) at org.apache.nifi.NiFi.main(NiFi.java:42)

I already added the "org.apache.nifi.management.server.address=127.0.0.1:9990" in properties file but that didn't work too what I should do ?
