Hello everyone, I need a VBA expert that can develop a functionality for trial/activation key.
I am basically developing a VBA Excel app where I would like to add an activation key module with the following characteristics:
1. User can test the excel for 7 days for free
2. After 7 days the application opens an input box (or hidden sheet with input format), asking the user to add an activation key/serial code
3. if he does no enter it or enters a wrong one (three times) the user cannot use the application anymore
4. if he enters the correct serial code, the application is now open and can be used only by this user/machine
5. if the Excel app is used on another machine, the process restarts: 7 days free and then asks for activation key
Overall the application can work on 20 different serial codes that I would distribute randomly to users purchasing the application. I need to have also the possibility to enter more serial codes for further distribution.
