Load error code 15: could not load default data

[proper]

I recently installed Labview 8.2 on my Labview 7.1 machine.  I can open up a VI (created on another labview 8.2 machine) on my machine and can save the VI to my machine.  But when I try and open the saved VI I get the following error:

"Labview:  Unflatten or byte stream read operation faild du to corrupt, unexpected, or truncated data.  An error occurred loading VI 'Filename.vi'.  Labview load error code 15:  Could not load default data."

Please advise.

Proper,

Can you tell us anything else about the VI in question?  For example does it use any driver VIs, such as DAQmx?

One thing you may want to try is saving for the previous version of LabVIEW and then reopening the file.  You can do this by selecting File»Save for Previous Version... and selecting LabVIEW 8.0.  The internal conversion process may clear up whatever is stopping LabVIEW from loading your VI successfully.

Also if you don't mind sharing your VI with the world you can upload it here and I can take a look at it to see if I see the same behavior and/or offer any more specific help.

The VI uses NI Vision, which I did not have installed on my machine.  I hit 'ignore' when the VI tried loading vision items, as the changes I was going to do did not apply to the vision section of the VI. 

I went ahead and installed NI Vision and looks like that solved the problem.

Thanks.
