Programmatically editing VI Description

[Chris_12345]

I am trying to programmatically edit the VI Description for a large set of VIs. Seems like it should be very easy, but it doesn't appear to work. I can read the VI Description text fine, but when I try to write to that property, nothing happens. The text does not get edited, and no error is reported. What am I doing wrong?

NI documentation says that the VI Description property can be programmatically set:

Thank you for your help.

You need to save the VI after you update the description.
