error of version

[sole]

hi!

use a 7.1 version, before I used a 6.1 version so I have some .vi which are compiled with the 6.1 how can I do to used them with the 7.1 version. I have tied to open them but I can't, the message error say that there is no diagramm.

Labview: VI version is too early to the current version .
I hope that you have a solution
thanks

When you save the VI, you have the option to remove the diagram (the source code) and be left with the compiled code. The problem is that when you want to run the VI in the newer version, it needs to be recompiled, and for that, it needs the diagram.
You need the original VI (the one with the diagram). If that wasn't kept, you will need to rewrite the VI.
You should always keep at least one copy of the source code somewhere.

thanks for your reply but the issue is that the .vi which are compiled with 6.1 have no diagram because it wasn't my .vi. Is there a test version of labview 6.1 to see if it is this error?
thanks

I don't know if there is a demo version of 6.1 available, but I don't think this will help you, anyway. If the source code has been removed then it's gone. You can't restore it. Unless you can get whoever wrote the VI to send it to you with the diagram, or at least compiled in 7.1, you can't use it.
