Always Crowd ('s tomcat) is not starting caused by a 'not a valid Win32 application' error

Recently I have set up the Crowd instacen on my Windows Server 2012 machine. I have set it up as described in its documentation and configured it to use a separeate mySQL DB. Running Crowd from start_crowd.bat works fine so far. But I need to run Crows as Windows' service. I installed the service as described in the ducmentation again an altered the jvm settings as recommended. Starting the server from bat-file still works proerly.


But if I try to run the Tomcat/Crowd service, it stops soon after startup. Attachted there are the logs, presented until the services crashs in debug log level. For configuration I have upgraded my Java installation to version 9 and ensured, that JAVA_HOME is pointing to the directory of the jdk.

Result of JAVA_HOME system variable output:

echo %JAVA_HOME%
C:\Program Files\Java\jdk-9.0.4 

Results of Java's version:

C:\>java -version
java version "9.0.4"
Java(TM) SE Runtime Environment (build 9.0.4+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.4+11, mixed mode)


I have no idea anymore, why the service is not coming up? Is there maybe a issue because of Java's 32/64 bit installation / expectation?


Thanks in advance,

Hi Kevin,

You guessed it! It's Tomcat that is expecting the wrong Java. Please follow Crowd 2.8 service 64-bit fails to start - not a valid Win32 application

On a side note, Java 9 is not a supported platform for Crowd, so unexpected behavior could result. Please change to a supported Java version listed on Supported Platforms.

Best of luck,


Hi Ann,


thanks for your reply and the workaround. I fixed the problem with exact this solution. The tomcats runtime was for 32bit system; Replacing them with the ones for 64bit system solved my issue. Crowd now comes up via service and runs without a problem.


Thanks again and best regards,
