I mean at run-time, since obviously there are users with existing installs and it's going to be a support headache.
Yeah, a crash might be the only user-visible indicator. A +reg trace should reveal the user SID, and if +advapi shows calls to GetTokenInformation(TokenUser) and LookupAccountSid it's likely that the app depends on the SID <-> username mapping.
