How do I get rid of trial version messages in software I developed

[bigfoot104]

I have a VB6 program for testing our equipment.  I have it installed in many places.  Recently I made a change to it, recompiled, and installed it.  Now, when I run the program, it is saying that I am using a trial version of the OCX controls.  My S/N is J13X29523.  Please advise.

bigfoot104,

Did you recently install a trial version of a newer version of Measurement Studio?  This KnowledgeBase article addresses the error you are seeing: http://digital.ni.com/public.nsf/allkb/60B1DE0C85624B55802568D90031AF89?OpenDocument .  Have you tried running the license fixer utility specified in that KnowledgeBase article?  If you try that, and that doesn't work, try uninstalling Measurement Studio and reinstalling it, then deleting all the Measurement Studio controls from your user interface, save/compile the project, and re-add them.

If that doesn't work, what happens when you create a new project and place a Measurement Studio control on the form?  Is that control unlicensed?

It can get even worse than having the annoying message pop up.  Typically, they will replace the CWUI.OCX with the latest version.  Then the UI objects properties get set to the default values when you load your project and you have to re-set all of the properties that are not at the default setting.  It is extremely frustrating - I have complained about this many times and have never recieved any explanation as to why NI persists with this- it can be extremely frustrating.

The problem in this case is that my installer program pointed to an old version of cwui.  So it was my fault.  On my test machine, everything worked correctly, but when it was deployed the message came up.  When I looked at the datestamp on the installed version, I realized that the msi file contained the wrong version.

Thanks for your replies.

Jason,

What exactly causes the properties of your UI controls to change?  Is it when you're upgrading, or uninstalling the eval version and installing the new version?  I just tried testing this on my machine (making a project with a graph, changing properties from the default, upgrading Measurement Studio), and my project has the same graph control with the same properties.  If you provide some more detail about what you are doing when this problem occurs, I can try and reproduce it and figure out what is going on.
