Hello,
Each GUIKit definition by default runs within a protected $ContextPath
which does not include the Global` context.
When you call Install[] on your function outside the definition above
the symbol HSeg is most likely in the Global` context.
You can include the Global` context with the call to GUIRun above
using the option IncludedScriptContexts -> {"Global`"}
You can read more about how contexts are handled with GUIKit definitions
in the Help Browser documentation under
GUIKit -> Building GUIs -> Advanced Topics -> Scoping of Scripts
