Hello everyone,

I am not able to open four apps: Mail, People, Calendar, and Messaging. Other apps are ok except the store. Can you guys open them? Eachtime I tried to open, it shows me a message - "(App) can't open".

In addition, I cannot sign in to the store. When I click the sign in button, nothing happens.

I have tried a system recovery, but the issue remained.

What can i do? Thanks.

The Metro apps are the most incomplete portion of Win 8. Which version of Win 8 do you have, CP or RP? If you installed Win 8 CP, the next version, Win 8 RP has been released. I would try a clean install of Win 8 RP.

Hi Ted.Thanks for answer. I am runing RP now.

Hmmm, I would have to say your installation is corrupt. Those specific apps work fine in my installation. How did you install Win 8 RP?
