Windows 10: Calculator in Win 10 is not working.

Tried to use the built in Calculator in win 10 this morning and got the following message:

THIS APP CAN'T OPEN
Your trial period for this app has expired. Visit the Windows Store to purchase the full app.

I've used the calculator numerous times with no issues. I've never bought anything from the Windows Store,

I thought Calculator was part of the Win 10 operating system.

When this message pops up I cannot start any other program. I must hit Cancel.

Why am I getting this message and how do I restore use of Calculator.

Thanks.

:)

Hi, see:
Windows 10 "Your trial period for this app has expired. Visit the Windows Store to purchase the full app." problem - Spiceworks

and for reference
Apps - Reinstall and Re-register in Windows 8 and 10

 

Thanks dalchina. Item number 1 worked. Calculator is back.

Why was this necessary since I have been running Win 10 since day 1?

 

Goodness only knows - I was once asked to rate it *What

 

Good. Often worth checking the tutorials here.. excellent, practical.

Why? Cosmic rays? Magnetic storm? Random chance? Power glitch? Nothing's perfect. It can be said hard disks work on a statistical basis... not hard 1's and 0's.
