Error 7 occurred at invoke node in CMP Get VI Hierarchy.vi

[jht LabView]

I get this Error 7 when doing compare VI hierarchies for two VI.  I clicked on continue but the program will not continue.

Hi John,

This has previously been reported to be caused by one of the hierarchies not being of the same version of LabVIEW as the other. The workaround is to mass compile the old VIs by going to "Tools » Advanced » Mass Compile..." and selecting the directory or library that holds the old VIs.

Let me know if that doesn't solve your issue, thanks.

I tried to mass compile per your suggestion but it still doesn't work.  When I mass compile, I get errors that some VIs cannot be saved.  Does Compare VI Hierarchy available in LabView 5.1 or 6.1?

Hi John,

Yes, the feature to compare VI Hierarchies is available on 5.1 and 6.1. Remember  that you cannot mass compile a VI if it is saved without the block diagram because the compilation process works by converting the block diagram into compiled code.
