I have a dynamically dispatched VI called "Insert Into HAL.vi" that inserts HW objects into my HAL. In the image below, you can see the Choose Implementation window that allows me to select the specific implementation when I double click on Hardware.lvclass:Insert Into HAL.vi. All three frequency counter options are grayed out. Those options are for the classes Frequency Counter.lvclass, 53131A.lvclass, and 53220A.lvclass. I don't understand why these are grayed out. All three of these objects have an implementation of Insert Into HAL.vi and none of them are broken. Why are these three grayed out in Choose Implementation?

Choose Implementation Windows Options Grayed Out

Thanks for getting back to me, Matt. I did just call NI with a service request today. I sent that apps engineer a zipped version of what I have, so he'll be taking a look at it.
