Problem:
When I try and save a VI I have created in LabVIEW 5.1.x back to LabVIEW 5.0, all of the save options available become grayed out. Why am I not able to select any of these options?
In LabVIEW 6.0 and above, when I try to save for previous version, why are some versions not listed?

Solution:
LabVIEW 5.1
When you try to save for a previous version in LabVIEW, the available options are determined automatically.  The options will be grayed out if the file you are trying to save is not compatible with any previous versions.

You may be using functionality that is LabVIEW version specific, and not available in LabVIEW 5.0.  It could also be related to the inclusion of tool-kits.  Toolkits cannot be saved for previous versions of LabVIEW.  This is because toolkits have their own versions, and you can only have a toolkit installed for one version of LabVIEW at a time on a machine.
The options are set to save all VIs in the hierarchy excluding the VIs in vi.lib.  The code that is incompatible may not be in the top level VI.  You should check through each of the VIs in your code and see if you are using toolkits or version specific VIs.  

LabVIEW 6.0 and above
In LabVIEW 6.0 and above, the incompatible options do not display in the dialog box when choosing to Save for Previous Version.

Keep in mind, each version of LabVIEW before 8.0 can only save for one previous version.  In LabVIEW 8.0 and beyond, you will see each of the versions of LabVIEW for which your code can be saved.
