Can I generate License key for installer made using ApplicationBuilder of LabVIEW - labview

Hi Nac ,
Yes, you can customise your application like other softwares.
You can use different ways for that.
one way is to read physical address from the system wherein you load yur application,manipulate it  and keep whole vi ina case statement fulfilling the criteria of being that manipulated data equal to what you enter.....
hp you got an idea of how to do it.
best wishes and regards !

Hello,     I am not able to find any link of how to make the passwords or license keys  so that i can use that information in my application for code locking? I am not getting any discussions on this topics after giving search words that are suggested by NAC. Nabhi

Hi Nabhi, Here are some of the discussion forums that I found that have relevant information for you:<a href="http://forums.ni.com/ni/board/message?board.id=170&amp;message.id=13070&amp;requireLogin=False#M13070" target="_blank">This</a> discussion forum even has a screen shot on how to password protect your VIs.

Hello Karunya, My question was different. I want to distribute an application that asks for serial number / licence key while installation and the licence key should be generated considering the MAC address of serial number of hard disk etc etc.. as explained by one of the replies in this thread.... quote below" one way is to read physical address from the
system wherein you load yur application,manipulate it&nbsp; and keep whole
vi ina case statement fulfilling the criteria of being that manipulated
data equal to what you enter....."Password protection of vis is different. I am looking for generating a product key or license key for an application that is developed by application builder. eagerly looking for the reply to my question.

Thanks u all for ur nice reply.
i will try&nbsp;to elaborate in other wordings : I want to&nbsp;ask user to enter unique product code at the time of installation only and every time user runs exe.
Awaiting for ur valuable replies.

Hi, You can password protect the zip files itself. The installers does not have any kind of password protection. It creates a Microsoft installer and the utility that microsoft uses is required to edit the configuration of the installer itself. The only other option would be to create a password that would prevent it from executing. However, you will still be able to install the program.Good luck!

Dear Karunya, &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I understand password protection of vis and zip files. But if the application is given to one person and he can give it to some one else with the same password. So the Vis or Executibles are no more password protected.&nbsp; I was thinking of having a system where, while installing the s/w will check for the mac / h/w address and applies licence key and then execute the program. If the password of Vis is known to one , any one can use that with the same password. I think i am not able to put my question properly. I hope my question is clear now. regards, Nabhiraj

Hi Nabhiraj,
That is not possible using te LV Application Builder/Installer. :smileysad:
You have to write an installation script using Installation Shield or something alike...

One possibility is to have the installer run a simple program after the installer runs (Use the Advanced tab on the installer build page.)&nbsp; This program can ask for the user 'key' and using the SID generate a unique serial number that is stored in the registry (or elsewhere).&nbsp; Your main program could then check this key and determine if it is to run or not.
&nbsp;
Not a perfect solution, but it is a bit better than nothing.
