I have the same issue today.
Actually, I updated 'Extras & Info' once already with no problems. Today I noticed a new notification for another update, and now it seems to download about halfway, then gives me an error and says it can't be completed. I tried both over wi-fi and cellular.
When I look for 'Extras & Info' now in the settings, its gone and replaced by a path name "c:\data\programs..."
I cancelled the update, then rebooted. The 'Extras & Info' is still gone from the Settings, and now the Market doesn't even indicate there's an update anymore.
Well, at least it was for something non-essential.
