I'm having problems installing AEM Forms 6.2 on clean Windows Server 2012. Installing 6.1 works fine. The first problem occures when I try to change the administrator password in "Adobe Experience Manager Web Console Configuration -> Adobe LiveCycle Client SDK Configuration". The log shows errors as below. Changing admin password in admin-ui works fine. What have I missed? Are there JAR-files missing someplace? Sorry for the formatting mess. IE 11 or Edge can't handle the editor-JS on this page. 10:55:52,260 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/lc]] (CM Event Dispatcher (Fire ConfigurationEvent: pid=com.adobe.livecycle.dsc.clientsdk.internal.DSCConfigService)) ERROR: EventDispatcher: Error during dispatch.
