Removing existing permissions on a folder

[Nick_Umanski]

I was required to give all users (Everyone) full access permissions to the INSTALLDIR for our product. This I did and the product was released. There was then a change of mind and for the next version of the product I was asked to remove those permissions, which again I did.

Works as intended for a fresh install. Problem is if the customer installs the old version and then upgrades, the permissions set by the old version remain in play. How can I remove the permissions already in existence on a folder?

Thanks in advance.

I think your best bet is a major upgrade by changing the product code in the main view of your project.
This will perform an uninstall and new install.

And if you can't do as Georg1 suggested... do it with a custom action using ICACLS.
