Software Deployment

While I have no way to give you practical advise on this case without actually seeing the contents of the package, you should know that shortcuts are not the only advertisement mechanism available in an MSI. I believe there are a total of 5 tables that can contain advertised entrypoints, i.e. Class, ProgID, Mime, Extension and Shortcuts, but there might be more, you should look it up :-)

If you can populate one of these in your package you should be able to trigger self-healing even without a shortcut.

Create an SCCM program to install your MSI (with no Active Setup) & set it to run ‘Only when a user is logged on’. On the Advanced tab, under ‘When this program is assigned to a computer’, set the dropdown to ‘Run once for every user who logs on’.

pjgeutjens or Andys0123 are probably you bet bet. I have never had to do a class or extension entry point/self-heal but know it can be done. There isn't a whole lot of info about it, since most use shortcuts.

Though the argument against active setup, applies also to advertised entry points/self-heal. (Conflicts with SCCM installations).

Thus Andy's solution is probably the better one, since SCCM will manage its installations in order.

Normally I'd say to use an advertised shortcut. However, since it's an internet add-on, there most likely won't be a shortcut that the user will launch to trigger that. You could put some things in the default user profile, but that won't help the users with existing profiles. IMHO, you're stuck. Maybe someone smarter than I has a better idea.

Active setup is the only solution for these cases. What conflict does it have with SCCM deployments?

Adding to my previous comment, have a look at this link:

The vbs solution at the bottom might be interesting to you, basically triggering a selfheal at each logon if needed for that specific user through a ..\CurrentVersion\Run key. It seems more robust to me than an ActiveSetup solution..
