Missing VIs

[Rick100]

Labview DAQ application that was working pefectly has errors after reinstalling on a new computer because of HD failures.  The applications uses a Hytek iUSBDAQ DAQ.  The full set of Hytek drivers are installed but I don't know what to do about NI drivers (I also have a NI USB 8008 DAQ but no immediate need to use it).  Here are the error messages:

   Front Panel Errors

Type Definition 'Device Type': cannot find valid Type Definition

Type Definition 'Input Range': cannot find valid Type Definition

Type Definition 'Start Channel': cannot find valid Type Definition

   Block Diagram Errors

SubVI 'iUSBDQ _EnumerateDevices.vi':subVI is missing

SubVI 'iUSBDQ _OpenDevicesSession.vi':subVI is missing

SubVI 'iUSBDQ _ReleaseDevices.vi':subVI is missing

SubVI 'iUSBDQ _StartStream.vi':subVI is missing 

   Details

The subVI could not be found when loading this VI.  It may have been moved,deleted, or its name may have changed.

Both computers where this functioning program was installed have failed but most of the files were recovered.  Should I look at the recovered files and if so, what do I look for?  Or, is there some way to rebuild the missing VIs?  

Any suggestions will be greatly appreciated.

Thanks,

Rick

Hi Rick,

it seems the Hytek installation is not completely done. You're missing VIs from that driver installation...

So (re)install that driver with all LabVIEW-relevant parts... When this has been done you will find the missing VIs in their expected place.

I am runnning version 10. Software is running fine. But I am missing three "While Loops" I can't see the missing loops after using navagation menue? I am looking for back ups from last week.

Hey pnielsen,

Can you give some details about your application?  Are you using the same Hytek device that Rick mentioned above?  Can you post a screenshot or copy of your code?

Please post back with details and any additional questions.

Thanks for the feedback. NI tech support called. If I run my program in Version 2010 it runs with missing While loops in the block diagram. I tried to run the same program in version 11 and it won't run. I am totaly stumped. I send screenshots to NI. This a week I should have taken a vacation and not returned. This anomolie is really doing a job on me.

Hi max,

welcome to the forum!

So you ask in an unrelated and old thread for some missing subVIs without mentioning which VI you want to open?

Please create new threads for your own questions…

(Solution: ask the programmer of that VI for the needed subVIs!)
