Labview license turned from licensed to 30 days evaluation

[sunflower2772]

The other day I bought and installed a NI Developer suite and registered the product through the internet. When I start Labview to edit vis I can see the following screen showing that my Labview is licensed forever.

But after about a few weeks, to my shock somehow my Labview turned into a 30 days evaluation license. I waited up the 30 days, and my Labview really expired on the 31st day and I cant use Labview anymore! I do remember I registered Labview on the net and got the screen above, so is the engineer watching beside me. I registered again with a different method by calling up National Instrument vendor and gave the vendor my PC number and he gave a long key for me to type in.

I am still a bit worried that this kind of incident might happen again, because I have shipped the PC to customer with Labview still in the PC and a exe file (not setup file) that the customer use to log his data. I worry that some weeks later Labview might suddenly expire and the customer could not run the exe file anymore.

So have you guys experienced any incident like this? What was the problem? Did I missed something in the first registration with the net? Thanks.

You must license the development environment. Applications build as exe will run without an license as along as you do not any special module included like Vision. For Vision you need a special runtime license.

I have never seen this for LV up to 8.6. LV 2009 is not so long installed reaching the 30 day limit.

I haven't seen this with any previous installations either. I will also mention that you do not need to ship the computer with the development system installed to get a LabVIEW developed .exe to run, it only needs to have the LabVIEW runtime engine installed, which is a free download. No licenses are needed for it or the .exe you developed, except in the case of a few addons, the one mentioned before, increased "seats" for web access, and possibly a couple of others that aren't coming to mind at the moment (DSC?).  You can go on the NI website to determine the status of your licenses, on Windows systems, by going to the National Instrument folder under the Windows' "Start", "All Programs", "National Instruments", "NI License Manager", which will display the license status of all installed NI software on your machine.
