Registration of the app failed with error 0x80073CFD

Delphi had Access Violations, Visual Basic threw Out-of-bound-index errors and COM+ had frustrating locked DLL’s. Deploying windows mobile apps introduced a new type of message: “Deployment failed”. And often you have no idea why it is happening.

While creating a Windows 10 app in Virtual Box on my Mac, I got this one:

Registration of the app failed. Deployment Register operation with target volume C: on Package ***
(c:\users\loek\documents\visual studio 2015\Projects\App4\App4\bin\Debug\AppX\AppxManifest.xml)  failed with error 0x80073CFD.

build error

Update Windows 10 to fix it

I deployed a few Windows 10 (universal application platform) apps before so I knew it should work. I remembered that Windows 10 rebooted earlier to perform an update. So I checked the update status and this is what I saw:

update windows 10

Apparently Windows updated (or not) but needed more attention! Let it update until you see:

restart windows 10

By the way, I love the ‘several times’ in the previous screen

Perform the Restart by pressing OK. A new (cool) screen appears:

updating windows 10

Wait until it finishes and after that you should be able to build and deploy your apps again!

This was not the first time I solved a deployment and/or registration-problem by updating Windows. I hope this helps you too!
