I just did a build with 1170 for both Android and iOS, both built successfully.
The null error could be a syntax error in a module that you’re not using but is sitting in the folder. It could be a certificate/provisiioing profile problem too.
Hmm, I don’t think it is a certificate /provisioning profile issue since I can build another project just fine with the profiles.
And I am not sure where the syntax error could be as the only two non-Corona modules that I have loading that are not in the other project which builds, have not been changed since I last built and there were no errors there.
How do you track down an issue like this?
Hm… do I need to say Corona where to find the jdk? I´ve set everything to standard during installation but it did not help
The console keeps saying: _ CoronaBuildMethod overriden. Using: Corona.build.5. _
The JDK is usually in the path, so its found automatically. One problem that can happen is getting an older JDK in the path. Let me see if I can get someone with more Windows experience to help you.
That would be great, thank you! 
One of the Engineers got back with me and generally that error is not related to your Java install. We just want to make sure that from this machine, using the latest daily build, you cannot build the Hello World app? Also when you respond, if you can provide me the date and time that you tried to build so we can try to look in the logs and see if we can find anything.
Okay,
I tried it at 4:44 pm (GMT +1) with daily build 1170.
Project Name: “HelloWorldLocalized” <— sample app
I will try it again at night.
I tried it again - just a minute ago.
I’ve passed this information back to Engineering but it is the weekend, so I probably won’t get an answer until next week. Hopefully they can look this far back in the logs.
I´ve downloaded daily build 1172 and tried it again - 4:49 pm (GMT +1)
This is the root of your problem. Somewhere in your registry ( probably HKEY_CURRENT_USER\Software\Ansca Corona\Corona Simulator\Preferences\ ) , or potentially in your build.settings (though it shouldn’t be in the sample code) there is a reference to corona.build.5 that needs to be deleted. This was something that was used at one point very briefly for a beta test and is no longer needed.
@Seanh: Thank you very much! This has solved my problem!! You are right, at some point I had to add something to my registry in order to beta-test project Gluon 
This might help others in a similar situation.
Thanks,
