Set folder permissions with Setup Factory 9.0

Hi,

I'm trying to install some files to the Application Data for use by all users on a system but it seems that permissions in that folder do not allow read/write permissions to all users by default.
I have read the post on this topic in the old version forums but it seems the installer is only for Setup factory 7 or 8: past topic.

Do you know if there are updated script files available or if there is a better way to go about this?

Thanks!
