@user2614235 Your questions are likely down voted because they lack investigation on your part, as well as they lack a clear description of the problem you're trying to solve. My comment was intended to be tongue-in-cheek so you can update your question to include an actual question that someone can answer.
From looking at your post, it is impossible to know what potential problem (if any) you stumbled upon. If you have a specific problem, we can provide you with a specific solution (or at least point you in the right direction).–Jun 3 '14 at 19:12. The simple solutionThe simple solution would be something like this. When the user buys your software, generate a unique GUID for the license. Let's call this the license key.
When the user installs the software, you take your unique hardware key, concatenate that with the license key, and hash the result. The hash you generate will be the activation code that you're looking for. Store that value on your server. If the same license key is ever used to install the software on another machine, you will compare the computed activation code for that installation against the one you have stored on your server and deny the installation if the codes do not match. The CatchThat being said. The way your current scheme is set up, you are going to risk making your customers very upset. For example, if I buy your software and my hard drive dies on me, with your current setup I would have no way to recover my software.

If you're going to do hardware signature based licensing, you should try to restrict it to the features that are least likely to change. BIOS.ok maybe you're safe. But hard drive, network card, video card are much more likely to change.Also, you might want to give your customers a way to transfer the license to another computer. The way your do this is have a custom action in your uninstaller that will revoke the activation code for the license so it will no longer be tied to that hardware ID. ConclusionIn all of this, the key is to keep things as simple as possible for your customer. There obviously is a trade-off between security and ease of use, but you DO NOT want to lock out legitimate customers and risk alienating them.All that being said, there are also plenty of existing commercials options for managing licenses. Is pretty good is you're willing to shell out the money.

In everything, just consider the cost of securing your software versus the value of securing it.
