Xls Padlock Activation Code (Mobile)

If you purchased the file but lost the email:

Open the locked Excel file. Look for a splash screen or an "About" tab within the padlock dialog. Often, developers embed their email or website.

For professional software distribution, XLS Padlock allows your application to "call home." When a user enters an activation code, the EXE contacts a web server (which you manage or host via a service) to verify if the code is valid, expired, or already in use on another machine.
