Thanks, dilettante, for an interesting and very relevant discussion of the issues here. But do you have any practical suggestion for how I can actually resolve this? We have an MSDN subscription, so we can download and use whatever Microsoft has. I've seen lots of references to Visual Studio Installer 1.1, but Microsoft has pulled that from its own sites, and seems to have strong-armed everyone else into removing all third-party download links to it. Is there some tool I can use to deploy this VB6 application to my end users? Those end-users don't have admin privileges, and I seriously doubt if management will consent to giving them those privileges.
