    dsdsds you can always install a crack for awail. Then once you believe that you have tried it enough buy the program.

    "cracks" are illegal. If I wanted to crack, I have all the info I need and that's not why I started this thread. Thanks everyone but I didn't get the info I needed. I don't care about resetting the trial period anymore because I found some great freeware.

    I'd still would like to have complete control over my windows registry and get my hands on a good uninstaller.

    there are only 2 ways to do what you want:
    1. export the registry before you install.
    2. find a registry tool that marks new registry entries.

    sangeetha: the registry is not the place you want to use as it is to easily edited you need to hide your data somehow, maybe hashed inside a data file where its not to easy to find and alter.
    Then if your really funny you figure out how to do random crc check on the files to prevent tampering.
    How ever the best solution in my opinion is the stop all this protection stuff and focus on your programs main objective, if you prog. is any good people will buy it.

    Indeed. I have bought software in the past for being good. Although I didn't need to buy it necessarily.

    A good book on the subject would be Crackproof your software

    There are some rather interesting concepts within the book, like Kunax mentions though don't store data in the registry. Some people try it by encrypting the keys they use and placing them in "Common" registry strings, however most people that will attempt to circumnavigate your measures will use specific tools for checking both how their registry is altered before/during and after running your program, they will also potentially have programs running for checking what threads/calls your program uses while it's being run too.

    In some respects what you might want to do is write a method and then attempt to crack the method. You should have no problems doing so with your insider knowledge of what method you used. If you find a method you can't crack even though you wrote the method, then you are probably safe with that method.

    which brings us back to wasting time on attempting to "protect" your program.

    how about this instead, You develop some sweet program that gets pirated by everyone and there mutant sheep jeff and in that process get your program exposed to billions of users(even a few aliens from alpha centauri) who previously never would have seen your little hack job.
    more exposure = more buyers = more exposure = more buyers

    Ah! but Kunax, it's really dependent on if your little hack job is a program you wrote pretty much for yourself which you are allowing other people to use (Freeware/Shareware) or if you are actually intentionally trying to fill a gap in a market for people to purchase the software.

    Image that some of these programmers are like starving artists, they might go out of their way to buy Software Development Kits (SDK), other licensed products, better hardware etc. Using copy protection for them is an attempt to protect their investment and to make sure that they can afford to get better SDKs, programs and hardware for future upgrades of their software.

    Like the way game developers can work is they actually get a kind of loan from a distributor to pay the wages of their staff with the notion that the Distributor gets a big cut of the profits in the end result. For the most part the games developers concentrate on their games programming and it's actually the distributor that shelled out the initial money thats trying to make sure it gets it's profit from the game being sold.

    Thats why when people complain about certain software protection on certain games, they shouldn't really blame the guys that write the game if it minces their DVD-rom but the distributor for trying to maximize profit.

    I think it's a question of personal view points, i still think you will get further by focusing on your app. with the possibility of a nag screen mayby, i base this on the small fact that people that don't intend to buy your hack'n'slach job are going to crack it anyway, no matter your protection.


    Game Developers and there Distributors.
    Thats a topic all by itself, game copy protection is becoming(is) quite aggressive at the expense of the user, but is it helping and do you want to alienate your customer?
    The games are still cracked, with in hours often and only a few of the "meanest" protection systems seems to be a problem. So does how does this help on profits?
    Your game is still cracked and you just shelled out a bunch of cash for some system that doesn't work.

    Anyways, I think the bottom line question is: which is most profitable?
    1. Attempting to protect your app with all its ups and downs
    or
    2. zero protection, hoping that people are honest

    :{) Note

    Try Installing it on an emulator of the operating system and then hopefully in theroy the trial will not carry on the conunt down as it is a guest os.

    USE THE EMULATOR

    Here's an idea...go to the store, take Nero off the shelf, take it up to the counter...then right before you get there, haul ass and run out the door yelling "Yahoo!!!"

    Your trying to do same thing. If the developers wanted you to use it past 30 days, they would have made it easy to re-load. That's the point of a trial period...you try it, if you find it useful, then you buy it.

    This is thread necromancy at it's finest, but it's inspired a couple of questions:


    Question: What is a good open source equivalent to Nero?
    2nd question: what's a good Nero equivalent for Linux?

    I don't get it. Nero comes free when you buy a CD-RW drive, OEM version. I've tried the Ultra Edition and I don't see anything new. The free OEM Nero does the job well anyways, so why trouble yourself on the Ultra Edition?

    Go google Total Uninstall 2.35, this is the last freeware version of this uninstaller, it basically scans the registry / directories and backs up the info during installation, this will totally remove any applications you install.

    There is a newer version but for some reason I find it more difficult to actually use, I'm not sure what the author was thinking when he began charging money for the newer version when the older is far simplier :shrug:

    When Crackproofing, this is one of the misconceptions that time is measured by the clock. It doesn't have to be, it can be measured by the time you spend with the program open, or even via some other references within the operating system. Furthermore there is then the possibility to ping time servers, although they too aren't infallible but it proves there are many ways to fix the circumnavigation of just the BIOS and OS clock.
