I am still unsure how LOB app deployment is supposed to work. My client successfully manages to screw up the installed apps when updating them. The devices have multiple users and each user should get the newest version of the app. But that does not seem to work all the time. I have a script that installs the app to the online Windows image of the device using

DISM /Online /Add-ProvisionedAppxPackage /PackagePath:"%~dp0%appx%" /DependencyPackagePath:"%~dp0%package%\Dependencies\x86\Microsoft.VCLibs.x86.Debug.12.00.appx" /SkipLicense

After update some users have the app then marked with a little cross. When launching the app it says "the app cannot be installed. Check the store". Which of course for LOB makes no sense at all. Where can I find a more detailed error description what's wrong with the app?

My client cannot use neither Intune nor any other "Enterprise" Server solution for deployment. They want to stick to the "USB way" of deploying the app and its updates.

Hi pkusawe,

A quotation from a Deploying enterprise apps.

To deploy the app through the Windows image:

Ensure the Group Policy or registry key to allow all trusted apps has been set. You can do this by using the following setting:

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Appx\AllowAllTrustedApps = 1

Use the Deployment Image Servicing and Management (DISM) command-line tool. For example, to install the package into the offline image, open an elevated command prompt and type:

DISM /Add-ProvisionedAppxPackage /PackagePath:C:\App1.appx /SkipLicense

To deploy the app at run time, use the appropriate Windows PowerShell cmdlet. You can do this by using PowerShell or any management tool that supports executing PowerShell scripts or cmdlets. For example, from a PowerShell command prompt, type:

add-appxpackage C:\ContosoApp\ExpenseApp.appx

Deploying updates

You deploy updates for an app in the same way that you deploy the app at run time. The updates must be installed per user for each user on a machine.
