Windows 10 How to fix 'this app can't open' on Windows 10 Technical Preview

[kemical]

Some users may find trouble opening the Mail,Calender and People app in Build 10041. Apparently down to a licensing issue Microsoft have blogged a solution here (it works too):

.

• In this build, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:
  • Open powershell as administrator
  • Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
  • Re-install Mail, People and Calendar from the Store (green tile)

This also works for Build 10049. I just repaired the Mail,Calendar and People app.
