I have .NET Framework 4.5.1 Preview installed.
The .dna file contains the following DnaLibrary tag:
<DnaLibrary RuntimeVersion="v4.5.1 Preview">
I get an error message from the Add-In Loader which tells me
"This Excel add-in requires the Microsoft .NET Framework."
I have also tried:
RuntimeVersion="v4.5.1" and RuntimeVersion="v4.5"
but I get the same error message. What should I do?

.NET 4.5 and .NET 4.5.1 are in-place updates of the .NET framework. As a result, the runtime version number does not change.
For all of these you'd use
Whatever is the currently installed update will be loaded. If you need to handle the situation where a newer update is not installed, you need to check the registry yourself in your AutoOpen.
