I'm wondering if
c:\Program Files (x86)\ is redirected somewhere else under win2008 Server R2.
The thing is, a service is supposed to add/change fields in the settings file stored in
Program Files (x86), but nothing happens.
It is possible that the program's settings are stored in another folder.
The folder AppData is hidden by default and you have to enable the Show Hidden Folders from Folder Options
No, it's not redirected at the file system level. However, UAC will "protect" directories that normal users do not have write access to and map those writes into the user's profile (I don't remember the exact location). The same will happen for other key locations (such as the Windows directory where many programs used to same ini files).
