[abifarz]

HI There

I wanted to to build a Application DLL or EXE from my Labview program  and give it or  sell it to another person .

but I have no Idea how should I protect it  to work just in one PC or in a Priod of time ?

in Visual C it is possible to make an Inastaller file including the licenc and Trial and so on by some software but how in Labview could do some protection ?

becuase I have checked :  if any body just with copy and paste of EXE file could run it in another PC which have installed Labview RUN Engine  .

this Program is cost me a licence of Labview and near to 1 year hard effort  , and the pepole that will use it are not reliable   :smiley  sad: ,

what shuold I do to prevent to use and run my EXE codes in another PC or more than a priod of time (2 yaers )

please tell me your Idea I will appreciate them .

Thanks

Babak

There is no built-in feauture in the application-builder to achive this. You will have to do it programmatically inside your VI. You could write a Key into the registry at first startup, and check this key whenever the program starts again.
