Labview dde.lib

[girish53]

I am using Labview 2020. I inherited an old vi which I am trying to open. I get messages about missing vis from dde.lib (DDE Request.vi, DDE Open conversation.vi etc). How do I fix this problem? Is there a way to upgrade the old vi to 2020 version? 

Thank you.

But don't try to find (and use) this in LabVIEW 64-bit. The CIN inside the lowest level VI is not 64-bit compatible.

Also if you try to upgrade an existing program that uses these functions it should find these VIs automatically (unless of course you try to load it into 64-bit LabVIEW).
