How to insert licence key

[cyberzork]

Where is the tab for inserting licence key? You could make it a hell of a lot easier to find.

If you installed eM Client from the Windows store then there is no license area to activate as per @Gary post below in the following thread.

Can´t activate my personal license after reinstall from Windows store

The MS Store version doesn’t use our licenses, but instead uses a monthly subscription you pay to Microsoft. If you want to use our licenses, please uninstall the MS Store version, then install eM Client from the link in the email you received with your license key.
