Sideloading Windows 8 appx Applications via ConfigMgr

  • Article

Hello All,

I wanted to take a moment and run through a few issues that you might run into while sideloading Win8 Apps in Configmgr.

For starters, here is the TechNet documentation on the topic:

Planning to Deploy Windows 8 Apps in Configuration Manager

https://technet.microsoft.com/en-us/library/jj822984.aspx

You’ll create the application using your appx by selecting the appx application type in the creat application wizard:

appx

When skipping the requirements noted in the TechNet doc above, you’ll hit a few issues.

After initial deployment, it failed with the following error:

The software change returned error code 0x800B0109(-2146762487).

If you look up 0x800B0109, It is “A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider”

I had to add the signing certificate used for my test app as a trusted root CA. You can do this via local certificates mmc or via GPO.

After doing that, I got the following:

The software change returned error code 0x80073CFF(-2147009281).

If you look up 0x80073CFF, It is “To install this application you need either a Windows developer license or a sideloading-enabled system”

This is because the system needs to have sideloading enabled.

Add the key to enable sideloading per the technet doc:

On computers that run enterprise versions of Windows 8 Enterprise, use this registry setting: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Appx\AllowAllTrustedApps = 1

Note that I’m testing on Windows 8 Enterprise, so I added the first entry. It didn’t specify in the document, but the value must be a string value.

The app should install after these steps.

Enjoy!

Ryan

    I think this was one of the original errors I had when I attempted to install this in my lab. Unfortunately I'm now getting 0x80073CF9. I've been investigating all morning, but wanted to see if you had any pointers.

    We figured out what was causing the problem. It's actually what you were blogging about in this post. This is the correct fix:

    "On computers that run enterprise versions of Windows 8 Enterprise, use this registry setting:
    HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindowsAppxAllowAllTrustedApps = 1

    Note that I’m testing on Windows 8 Enterprise, so I added the first entry. It didn’t specify in the document,
    but the value must be a string value."

    The only issue is that it isn't a string value. It's a DWORD value.
