How to set permissions to IniFile in WiX? - wix

Question

I have a component with an IniFile element in my WiX script. I need to set the read and write permissions for the Local Service to the resulting ini-file as the application runs under this account and must be able to read and write from/into the ini-file. The Permission(Ex) elements can't have IniFile as a parent so I don't see the native way in WiX to set permissions to an IniFile element, could anyone suggest a solution? The file is installed into a subfolder of CommonAppData.
The option to include a ready ini-file in the distribution and install it simply as a File is bad for me as the contents of the file depends on the individual installation (paths, computer name etc).

Answer 1

What version of Wix are you using? I am using Wix v3.9 and could get it to work. Well, I don't understand why the PermissionEx element would be concerned about the "Name" attribute of the File tab, especially when PermissionEx is itself nested/a child of the File tag.
Here is my sample project.
