Trial or Time limited versions

Hi

Is there any (simple) way to create a time limited version of a compiled script file? For example 30 days or 10 uses etc?

If there's nothing built in does anyone know of any 3rd party solutions?

Thanks for your time.

You could write the date out to a file and check this file each time the script is run.

Would not changing the system date get around this?

Hi, Yes. I understand now that the script would have to be a binary. However, as i have limited capability with Window Registry, where in the Window's Registry would i find that particular "key" in Paul's script?

In addition, is there any ways to prevent circulation of your own script? ie, when i send it to a particular client, i do not wish that he sends it to multiple of his associates. I understand that Paul's script actually stop working after 30days but it can be sent to multiple other computers...

My intention is to simple have something like a script that cannot be shared with others, and also expires on its own. Would that be impossible?


Making the script machine dependant would be difficult, what you could do is send a script to the client to run and e-mail the output to you.

This script could get system information, scramble it so the user does not know what you have. Then use this information in the trial script to check it is running on the correct machine.

The key in the example (it can be changed to whatever you want it to be) can be found using Start (type in the search box) regedit

and navigate to HKEY_CURRENT_USER > Software > Trial
