Hi,

Like you said, you can only make it more difficult, never impossible. Perhaps the simplest way to accomplish what you want, is building in more layers.
For example, you could add another xml file, with a nondescript name, and record the last access dates of all other files in the installation folder, upon installation.

At the moment your app checks for the date, you can cross reference it to the last access date of the xml file. If the combination isn't good, you know the user edited the xml file or copied the xml file from another installation. (On the other hand, using an xml file instead of say the registry, allows the user to simply uninstall the entire app and install it again. In any scenario, the xml files would all be recreated.)

You could also revert to confusion: name the tags you use for some other inconspicuous
object or setting that you are "checking".

Alternatively, or in combination, you could take the date you are recording now, take some other variable which value should be unique to this particular installation, or better even, the user's PC, and use them in some sort of formula, to create a code. Register the code somewhere else, and use it to retrieve the original installation date, and PC.

If you hadn't already thought of these yourself...

Good luck,

Johan

My advice is free, and you may get what you paid for.
