Question on software free trials

  1. Jul 10, 2012 #1

    I have a question regarding software free trials. Lot of proprietary software give free trials for few days. Now if I uninstall the software just some days before the trial period ends, and I re install it, does it give me the original trial period again ? How does the software know
    about this ?

    My guess: the supplier notes the ID of the computer when you download and keeps a record of the date. Presumably when you download a second time, the original entry can be referenced.

    It's also possible that the original installation puts a flag in the registry that will have the same effect as what mathman suggested.

    EDIT: but in ANY case, I'd be very surprised if you can find any substantial software that allows multiple installations of the trial version.
