I am trying to follow the weather module example and the build fails on the last line. My gateway is running, I am using a trial license, and time has not expired. How do I check if it is in developer mode? Any other suggestions? ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/0/0093ef44445ed733c8c94a169b4098b2c4353068.jpg) ---

If memory serves, that’s the error you get if your gateway isn’t set to run in Developer Mode. You’ll need to set that up first under Licensing. E: It will say “Developer Mode” on the top right above the “Launch Designer” link. ---

OK - It does not say developer above “Launch Designer” link. I am using a trial version of Ignition so there really isn’t much I can do under licensing screen. Is there a way to get this to work without a license. (I am resetting the trial license every 2 hours) ---

You’ll have to get a developer license to install (I think you can only use a trial version for this anyways). Check this link under “How Licenses Work”: [inductiveautomation.com/news/item/257](http://www.inductiveautomation.com/news/item/257) ---

Sure enough, that was the key. I’m all set now, Thanks ---

I recently have received a real license and installed it and now I am going back to work on my custom module again but I lost my developer ability so I can’t install the module I am working on. What do I need to do? ---

If you call support, or email, with your CD-Key they can add the “developer” flag onto it for you. Then you would just go in the license section and hit “reload license”. Regards, ---

Although, you might just want to keep things separate and have your real license installed somewhere, and then Ignition with a dev license on your development machine. That way your real system won’t say “Developer Mode” across the top all of the time. ---

[quote=“phassler”]I recently have received a real license and installed it and now I am going back to work on my custom module again but I lost my developer ability so I can’t install the module I am working on.

Modules can be signed by logging into the [Developer Portal](https://www.inductiveautomation.com/developers/login), selecting Module Signing from the links on the left and uploading your \*.modl file, (or you could just avoid all that and follow Colby’s recommendation).

No, you can’t enabled/disable it yourself, it is part of the license. You should have a production license and a separate license that just has developer=true and no non-free modules on it that you use for development. Support can set this up for you. ---
