Hi, > This may apply to FlexJS as well as Apache Flex
It’s the external scripts made to compile etc FlexJS projects that don't work on 4.6. The minor Flex SDK issues re the html template and initial code I can live with. > Have you tried this? Seemed to work for me. > http://blogs.adobe.com/flashplayer/2016/09/running-adobe-flash-builder-on-m > ac-with-java-78.html I’ve had it working on new versions of Java previously. Currently it seems to failing on getting a URL from Adobe to display the welcome page (or similar) and crashing :-( I’ve tried a clean install and also no luck. There a number of posts of stack overflow with other issues of it crashing on startup. I’ve tried all of the usual tricks to fix and no luck. When I did have it working on an updated version of Java I found 4.7 to be too buggy / crashed a lot so I went back to using 4.6 which seemed a lot more stable. Thanks, Justin
