I am trying to create a file system when installing a WPF application. Currently I am creating the filesystem at run time. I am able to use the FileSystem page in Visual Studio 2010 to create the filesystem I want in any folder except for Users\public.

In the installer Filsystem page I create a special folder, but I need to give my special folder a default location. I have already tried:
%SystemRoot%\Users\Public – it says it cant find it [Error: Cannot access network drive …]
And the other built in options go to places I don’t want the fiels to be, commonfiles/program files/user documents/etc.

Can someone help me with creating the file system under Users\Public?

The directory I want to create is C:\Users\Public\MY_FOLDER\MY_OTHER_FOLDERS…

    You want to use %SystemDrive% rather than %SystemRoot%. Check it with the Command Prompt.

    C:\>set System
SystemDrive=C:
SystemRoot=C:\Windows

    EDIT: To use environment variables in an MSI package, use the format [%Name], so in your case [%SystemDrive].
