Upgrade from previous version. New LabVIEW behavior

[ClaudioH]

Hi,

Today LabVIEW 2010 has the option "Save for previous version" because it upgrades automatically the VI to the current LV version (this happens since I use LabVIEW).

This behavior may cause headache when you are working with different projects that uses different versions of LabVIEW. If your last used version was LV 2010 and you double click a LV 2009 VI, it will be saved as LV 2010 VI and your LV 2009 project will crash.

My suggestion is, change the default behavior by keeping the current VI LabVIEW version and provide an option to upgrade to the new version.

Doing this everybody will be able to work with LV 2009 projects in LV 2012 without have LabVIEW 2009, 2010, 2011 and 2012 installed in the same computer.

Cheers,

Claudio: We'd have to ship every old version of the compiler and every old runtime engine with every modern version in order to support this. It's just not an option.

Hi,

I use LV 2010 SP1 and I have an option to "save to previous version" till 8.0. I want just the version that is actually possible to save to.

I believe that there is no problem to convert to LV 2010 SP1 a code produced by LV 8.0, edit it using LV 2010 in a temporary folder and save it again in LV 8.0 format in the original directory.

To produce a executable is a different issue if this is your concern.

I think that this behavior is possible to be achieved "under the hood" since it is done manually.
