ODK Aggregate App Engine Updater won't work

Hello, when I install ODK, at the end of installation i get the following message:

I have added the file: path to the Exception Site list, but still not working.

many thanks,

It sounds like you are using Java 9. Please uninstall and try with Java 8. We have an update coming soon that will add support for Java 9.

Many thanks, problem solved by using Java 8.
