@GrantBartlett Do we have any more specifics on this? The line mentioned in the comment isn't responsible for prompting someone for 3.5. That code section is only called if OUR parent installer script requests it.
We actually created the the following line in preparation for dotnet 7:

cncnet-yr-client-package/tools/build-installer/inno/installer.twig

Line 295 in 99f44fa

// Dependency_AddDotNet70Desktop

If people are being prompted to install 3.5, it's from somewhere else...
