I have been working on some software application and I update them every 6 months. Currently, the way I track the date is by extracting the date from the system when the user installes the application, encrypt it and store it in a file locally. Whenever the application is started, it checks if 6 months have passed, then it works or it doesn't, in which case it shows an error message telling the user to update.

I wonder whether there is a better way to do this.

Any comments or suggestions would be highly appreciated
