The first thing to do is to no try to write your own installer. It's nothing personal, but you're probably going to do it wrong. There are installation tools out there that already know how to get everything right, including permissions and uninstallers. I recommend Inno Setup. > In Vista, I run the setup as administrator (By manually check the related > box in its properties) and it will create the shared file, and after that, > when I write-click on the file to open its properties, I find the "Users" > Group is missing, I found "Administrators" and "SYSTEM". You shouldn't have to change the file properties of your installer just to make it run as Administrator. The OS will usually detect that a program is an installer and prompt the user for the admin password automatically. Regarding the file permissions, what directory did you create the file in? It should simply inherit the permissions of its containing folder. > My question is how can I programmatically add a "Users" group to the shared > file?

The permissions on that folder shouldn't need to change since everyone already has access to that folder. To find out exactly where that folder is on the target machine, use the ShGetFolderPath API function. I demonstrate how to call that in Delphi on my Web site: http://www.cs.wisc.edu/~rkennedy/my-documents Apparently, none of the links on that page work, so you can't get to the MSDN pages from there to fnd the list of CSIDL values. The one you need is CSIDL_PROGRAM_FILES_COMMON. Of course, you already know how to use that function, or one like it, since that's how you're finding out where the Program Files folder is anyway, and what it's really named. -- Rob _______________________________________________ Delphi mailing list -> [email protected] http://lists.elists.org/cgi-bin/mailman/listinfo/delphi
