[WiX-users] Protecting "config" files during an upgrade

[Chris R. <chr...@ma...>]

In a mistaken piece of design, one of our MSI packages ends up  
installing a file that we expect the user to then edit.

Unfortunately doing a package upgrade (or even just a repair of the  
current package, I guess) loses those edits by replacing the file.

Are there any attributes that can be set on the File to mark it as  
user-editable/preserve on upgrade? I'm led to believe that  
Installshield had a flag like this.

Cheers,

Chris
