Product key is incorrectly

Hi, today i've buy Parallels Desktop at the store.
I have created a account on Parallels. There my Productkey is activated, but when i try to install the program, it is not possible to use this Key.

 

Hi @MarkusH3 please provide us with your license key (you can send it via the private message), we will check it.
May be you purchased the upgrade version instead of the full license key.
