Hello,
To achieve what you need you can use our
Updater tool to deploy (without elevation) updates for your MSI setup.
This feature will install updates packages without elevation even on standard (non-admin) user accounts.
The only limitation would be that
the first version of your MSI package (that includes our Updater tool) have to be installed
by an admin user account.
Have a look over our
Handle updates without elevation article to get a starting point for how this feature works.
Hope this helps! If you have any other questions please don't hesitate to contact us.
Best regards,
Liviu
