Labview 8 crashes when using Read Labview Measurement File

[Nick_F]

Hi All,

I am a new user for Labview. I installed Labview 8.0 from the CD (evaluation copy). I was just testing the sample code provided by NI. I opened the "Load from File and Display" example and I was trying to open the properties for the Read Labview Measurement File component when Labview crashed. I tried it a couple of times and everytime it happens the same way (when I double click the component or right click on it).

I am using Windows XP with all the updates done. In the Windows crash report, the application version is 8.0.0.4005.

Other problem I encountered is a missing component on the Input Palette (no DAQ Assistant present) and the Instrument I/O Assistant raises the error "Measurement & Automation Explorer or the Instrument I/O Assistant is not installed correctly. Please install these from the Labview Driver CD". For the last problem, I will try to run the Labview Driver CD, once I get it. But I am not sure if the DAQ Assistant will show up then or not.

Any ideas?

Regards,

Nick

Hello Nick,

While it is not my area of expertise, I would expect the DAQ Assistant would appear after installing the driver CD as you said you would be trying.

What caught my attention was the crash.  The easiest way to resolve the crash is to delete the instance of the Read LabVIEW Measurement File on the diagram and place a new one from the Express Input palette (now called "Read From Measurement File").  In that situation, I would expect just pressing OK to accept the default configuration should work.  The crash occurs in certain circumstances when the Read / Write Measurement File Express VIs are dropped from a previous version of LabVIEW and then their config page is opened in 8.0.x.  This issue should be resolved in a future release, sorry for the inconvenience.

Hi Nick,

What you are encoutering is a known issue, and the solution is to upgrade to version 8.0.1 (free upgrade available from http://digital.ni.com/Softlib.nsf/webPreview/4C1209D42320BCFD8625711C005FB25B?OpenDocument )

With regards to missing the DAQ Assistant express VI - this is because you haven't installed the NI-DAQmx driver. When you install drivers such as DAQmx is will also install the relevant functions into LabVIEW so that they are available. If you don't have the drivers try searching on www.ni.com/downloads

Hope this helps!

P.S. feel free to rate my answer 😉

Thank you Jeff and Stuart,

Both of you have been helpful. I deleted the previous component (Read Labview Measurement File) and the problem has been solved.  After I installed the new Driver CD, I got the other components functional

Best regards,

Nick
