Windows 10 calculator error: You'll need a new app to open this calculator

I attempted to delete the regkey as suggested. When I navigated to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\[UserSid] the only id available was (Default) so I tried to delete
and the following message was returned: Error Deleting Values - Unable to Delete All Specified Values.

What should I do?
