Hi Giampaolo,

Welcome to PixInsight Forum.

On Windows XP you have to uncheck the "Protect my computer..."  checkbox on the confirmation window that pops up just before the updater begins copying files.

This happens because unfortunately Windows XP doesn't support UAC (User Account Control). PixInsight's update system is based on UAC and signed code for authentication on Windows Vista and Windows 7.
