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.
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:
Apparently Windows updated (or not) but needed more attention! Let it update until you see:
By the way, I love the ‘several times’ in the previous screen
Perform the Restart by pressing OK. A new (cool) screen appears:
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!
