Sideloading apps in SCCM 2012 R2

Hi all,

I am new to the Side loading of apps in the configuration manager. I tried to load an inhouse app which was designed by one of our developer but it gave a cert error.

What i did :-

1. Sat with the developer & build a package of the app using Visual Studio 2013.

2. Created an Application package in SCCM with the appx file in the package & deployed it to a windows 8 machine.

Error in AppEncore.log file :-

<![LOG[    In-line script returned error output: Add-AppxPackage : Deployment failed with HRESULT: 0x800B0109, A certificate chain processed, but terminated in a root
certificate which is not trusted by the trust provider. (Exception from HRESULT: 0x800B0109)
error 0x800B0109: The root certificate of the signature in the app package must be trusted.

How can we deploy the package & which are the certs i need, i checked the application package & there was a cert which was created when we built that.

Please suggest.

Thanks,

Pranay.
