When trying to install an application through SCCM to a Windows 8 PC, you get the following error:
In-line script returned error output: Add-AppxPackage : Deployment failed with HRESULT: 0x80073CFF, To install this application you need either a Windows developer license or a sideloading-enabled system. (Exception from HRESULT: 0x80073CFF) Deployment of package <<Package_ID>> failed because no valid license or sideloading policy could be applied.
A developer license (http://go.microsoft.com/fwlink/?LinkId=233074) or enterprise sideloading configuration (http://go.microsoft.com/fwlink/?LinkId=231020) may be required.
To help explain the To install this application you need either a Windows developer license error, first you need to know the requirements around installing an app in Windows 8.
When you try to deploy an app through PowerShell, DISM or associated technologies like SCCM to Windows 8, it interfaces with the Windows Store. Windows 8 will recognise the application as a LOB Windows Store app rather than a normal Windows program. Windows 8 handles Windows Store apps differently and requires that they are either authorised to install through the Windows Store or to be sideloaded.
For an app to be authorised to install through the Windows Store, you need to apply for a Windows developer license. This will then enable you to get your app listed on the Windows Store and install it onto Windows 8 computers without the 0x80073CFF error. This is obviously long winded and for most businesses who are just trying to install an application through SCCM. A better solution is to enable sideloading to the Windows 8 computer.
