I am trying to install the "Package File-Util" using the graphical Module Installer and get the message "failed 401 Authorization Required".

When I check the Preferences, I see that the active target folder is C:\Perl\site. However, it should be c:\Perl, but this option is marked as locked and I am unable to select it. In addition, I can find no way to unlock it from withing the application.

Any advice would be most appreciated.
Thanks.
