Can't download Developer app. I've never experienced this.

[AdamGebhart]

I just attempted to download and deploy an app to our local server and got the following message.  I am in Developer 1.18 and have used a few older versions and never seen this until today. 

I am wondering if this is related to a recent update of my PC from Windows 10 to 11.  The reason I say that is I have successfully downloaded and deployed two different 1.18 apps prior to the Windows update.

Has anyone else seen this and know how to fix it?

I don't know what's going on. The first thing I would try is running the Command Prompts in Admin mode.

I ran that as an administrator and still failed.  I did notice this in the command prompt window.

I don't recall ever deleting that folder and I don't see the same folder being in 1.17 or 1.16.

This error suggests you created a custom Theme called Master at some point and then removed it. Or didn't migrate it when you updated Experience Builder. Things to try:

• Add the Master Theme back to the your-extensions/themes folder with the client server off, then start the client server.
• If you don't want to use this Theme anymore, check all your projects Themes and set them to something other than Master.

Hmmm, I looked back at all the versions of ExB I've downloaded or used before (1.10, 1.11, 1.14 - 1.18) and none of them have the Master folder.

This specific app is one I built in ArcGIS Online then imported into Developer.  (This was the first time I've tried that workflow).  Do you think there is a chance it's related to that?

Yes, I think that is the problem. Did you download after the update on Oct 23? Themes were re-designed in the last update to something incompatible with the older version of Themes. And the entire application would be a version ahead of your Developer Edition.

[AdamGebhart]

Yes, that's exactly what I did.  Normally I just test things out in AGO, then build everything new in Developer.  

I suppose I'll test out a new Developer app in a little bit and see if I can download it.

[JeffreyThompson2]

Wait a few weeks for Developer Edition 1.19 to come out. It should be compatible with the version currently in ArcGIS Online.

[AdamGebhart]

Unfortunately this app needs to be published before Developer 1.19 is released, so I have to just build all new in Develooper.  It won't take too long though but I really wish I would have done it all in Developer to start.

Thanks for the suggestions.

@JeffreyThompson2  I finished building the app in Developer 1.18 and was able to download it.  I marked your comment about that as the solution.  Thanks.
