Create license key for My application

[Devan_007]

I am developing application software for industries . I want to create application I wants to ask key during installation (as labview asking during installation). Anybody Pls help?

LV2010 apparently has a tool for doing exactly this:  Third-Party Licensing and Activation Toolkit

I prefer to have more control over the process, though, and protect my software using the USB dongles from Matrix.  You just need to interface to a DLL to make it work.

Thank you for your reply

I am having LabVIEW 8.5 full development system only. This 'Third-Party Licensing and Activation Toolkit' will work over that ?

It looks like it is for LV2010 only.  But you might want to get NI to confirm this.

However, you could always develop your own licensing system.  I have done this in two different ways:

1.  Generate a license key that is based on the PCs MAC address.  You will need to have the customer call you and give you their MAC address.  Then generate a key based on this address.  Then the customer enters this key into their software.  This will prevent people from installing it on multiple computers.  One thing to remember is that the customer might have multiple MAC addresses, so your VI that checks the license key will need to check all MAC addresses.

2.  As mentioned, I have used the Matrix USB dongles.  I think these are great and they allow the user to run the software on whatever PC they like.  But it will require you integrate with Matrix's DLL.  And you also need to purchase a dongle for every customer.
