Aurora R8, Alienware update unable to retrieve system inventory

Do you have the correct AWCC installed?  The photo is showing an Area 51, but then the text says Aurora R8.  The picture doesn't match up with the text. 

I'm not sure where do you see Area 51. The screenshot shows Alienware Aurora R8. All the Dell software is the original that came with it.

The triangle case pictured is an area 51.

It's just a logo. The system is Alienware Aurora R8

Here's the client log:

The errors are in bold red. 

Looks like the dataset received has null values in it.... and the error is unhandled.

Anyways, the question is what's wrong with it...

Use a different navigator then.

Maybe pointless suggesting   

If you want to raise a bug and expect a new version corrected, I shall just fade away before I burn out 

Service tag is known to the app. In the log and image above i just masked it.

Thank you, @markburv !

Have you tried uninstalling Alienware Update, either using Revo or per Dell's Instructions: Dell's Instructions 

And then updating to the latest version (or, if the problem occurred after the latest version, rolling it back to a prior version? 

Current version:  4.1.0 <ADMIN NOTE: Broken link has been removed from this post by Dell>

Older versions: 

Yes. Both Alienware Update and SupportAssist. No luck.

Looks like there is something else that causes these errors.

Noticed that when is click System Info, it fails as well

Still no luck after uninstalling and reinstalling Dell-Update-Alienware-Update-Application-for-Windows_292RG_WIN_4.1.0_A00 and SupportAssist

For what it's worth, having the EXACT same issue with Alienware 17 R4.
