Open LabVIEW 2010 project with 2011

[flavienb]

Hello,

I'm working on a project which has been developed under LabVIEW 2010 and I just update my LabVIEW version to 2011. Nevertheless, I can't open some files with LabVIEW 2011. This include project files (.lvproj), class files (.lvclass) and some VIs.

When I try to open these files LabVIEW crashes and displays the following window :

Have you an idea of the origin of this problem ?

Thanks...

Are you using any XControls? Can you isolate specific VIs that are causing the issue?

Unfortunately this is not a unique problem.

XControls don't seem to be used.

I can isolate some VIs : for example VIs which are used for HTTP communication can't be opened. They are all in a same class and some of these VIs are calling VIs of the "LabVIEWHTTPClient.lvlib" library of LabVIEW 2010. Maybe it could be a source of the error ?

Have you tried mass compliling your LabVIEW after install?

[flavienb]

No I didn't try this. What is mass compiling ?

Mass compling make LabVIEW go back through all of the VI's and relink or refind them so that they are corret when used. It will take a long time for this to run so start it before lunch and it should be done after. I am not telling you that this will fix everything but it should help.

If you haven't done so already, please send in the crash report so NI can start to fix these issues.

[flavienb]

Ok thank you. I want to try this but I'm fear VIs don't work neither with 2010 nor with 2011...

[flavienb]

yes I already send the crash report to help NI to fix this issue

In your National Instruments folder you have separate sub folders for different versions of LabVIEW.  If you open a 2011 VI and mass compile it will affect the 2011 folder so your 2010 files are safe.  If there are any weird problems that do effect LabVIEW as a whole you will probably need to re-install LabVIEW completly anyway.
