and further many of them require internet but my customers may not be using it all the time One Question and Answer was related to functionality which is not what I want to reduceĤ. ![]() ![]() In another answer they checked with system date but as I told earlier I do not want to use that either.ģ. In one answer it is given that use "Rampart" but that is a paid application and I do not want to use it.Ģ. I have also read Create a trial version of a Java application, with limited functionality and How to create a trial version of a Java program but the answers given there were not satisfactory. So the idea I have in mind is that I put a count that how many times has the application being started, but where do I store the value in registry? (I have already read: read/write to Windows Registry using Java) So how do I make it trial after which it self destructs itself? I cannot put any other DRM as I have read that checking MAC address is a very bad DRM and after going through Making commercial Java software (DRM) I realised I have to make it somewhat simple. I have made an application in which I want that the application should expire after say 180 Days but the problem is that if I take the system date, anyone could just change it and get going and I cannot also take the internet date because many times the user will be working offline.
