Ouvrir un projet LabVIEW 2010 avec 2011

[flavienb]

Bonjour,

Je travaille sur un projet qui a été développé sous LabVIEW 2010 et je viens de passer à version 2011. Cepedant il ne m'est plus possible d'ouvrir de nombreux fichiers avec la version 2011. Il s'agit notamment de fichiers projet (.lvproj), classe (.lvclass) et quelques VIs. Lorsque j'essaie de les ouvrir LabVIEW crashe et m'affiche le message suivant :

J'espère que vous pourrez m'aider à identifier la cause de cette erreur...

Hi,

Thanks for posting on NI forum.

This forum is a worldwide forum, you have to write your questions in english.

This type of error seems to be a double read of your project, did you close the project in LV2010 before open it in 2011?

When you run your project, LabVIEW loads files or shows you the error immediatly??

What is the size of the project?

Could you try too recompile your project without launching it. When you lauch LV, click on " Option >> Avancée >> Recompiler... " and chose the project directory (You must have all files of your project in this directory).

Best regards,

Yes sorry I already post it in english after I saw it was a worldwide forum.

To answer your questions, the project well closed in LV 2010 before I open it with 2011.

When I open the .lvproj file, LV begins to load files then crash. The .lvprog file size is about 17 kb.

Thank you for your answer and I will try to recompile files with 2011 to see if it works...I take you informed.

So, I try to recompile files with LV 2011. But when I do it, LV crashes like when I try to open the project...

HI,

Could you describe a little your project, or it's confidential?

Do you have the possibility to create a new empty project in LV2011, import all your VIs and try if it works?

Regards,

[flavienb]

No it's not really confidential I can give you some informations.

For the moment I'm just trying to recompile source files of a LV project which enable to build a packet library. This library contains VIs for different functionnalities : communication (HTTP, TCP...), XML Parser, ...

The VIs are grouped in classes within the library.

I don't think the problem really comes from the .lvproj file, because the crash occurs also when I try to open some VIs.

Do you use LV optional toolkits or modules in your project?
Maybe you are using a toolkit that doesn't have active license

[flavienb]

Yes it's possible I didn't activate the licence for some toolkits.

I just remark something : I can open all the VIs contained in a class independently but when I try to open the .lvclass file it crashes.

[flavienb]

Concerning licences, it doesn't seem to have more activated licences for 2010 than 2011 :
