Deployment error in Windows Phone 8.1 app with capability Shared User Certificates in manifest

If I set my phone to install apps to the phone it works just fine. If I switch it back then I get the error.

It has something to do with SD cards!! Not the SD cards per-se , but the mech The only thing different was I installed a new SD card this weekend to my Lumia 1520 with Developer Unlock. I am running VS 2013 Update 4 and have a StandAlone Phone application using a Windows 8.1 shared app class. It was working before and now its not. same error as MAGNUS

With save apps to SD CARD setting in storage sense set If you use verbose build output it eventually says:

2>Follow the phone setting 2>Phone setting says apps to be installed to SD card 2>layout root folder: D:\WPSystem\SharedData\PhoneTools\AppxLayouts

With save apps to PHONE card setting in storage sense If you use verbose build output it eventually says:

2>Follow the phone setting 2>Phone setting says apps to be installed to internal storage 2>layout root folder: C:\Data\SharedData\PhoneTools\AppxLayouts

search your Detailed or "verbose" build output for the term "Phone setting says" That will get you close. Good luck.

I can confirm that VS 2013 Update 4 causes the error:

Error : DEP0001 : Unexpected Error: Package could not be registered. (Exception from HRESULT: 0x80073CF6)

My application was deploying to the phone fine before the update, and started failing immediately after the update. Modifying settings:

Settings/Storage Sense/Store New apps on my: phone

Solved the problem. Thanks Matt for the tip, saved me alot of time.

Try to uninstall current application in your phone, and run agian. For me its solved

This problem can be related to re-use of the same app template on Windows Phone (does not affect Windows desktop apps). In the Windows Phone section of the solution explorer, find your app manifest file (Package.appxmanifest), and review the following line near the top of the file (#'s in this example are representative, not actual):

<mp:PhoneIdentity PhoneProductId="12345678-1234-1234-1234-123456789ABC" PhonePublisherId="00000000-0000-0000-0000-000000000000" />

If you have re-used the same app template, then the PhoneProductId number must be different from one iteration to the next. I suggest simply iterating the last digit in the string (e.g., change 1 to 2, or 2 to 3, etc....). Once you make certain all your Windows Phone apps have individualized values in this field, you should be able to deploy them all independently.

It could also be a missing image in the Package.appxmanifest. Check the visual assets tab in this file (VisualElements in XML) to see if there is some logo missing.

I changed package name in Package.appxmanifest file. So I had to Uninstall app and Re Installation helped me.
