A new install of AWStats 7.0 (build 1.971) does not produce data in the Robots, OS and Search Key Phrases sections of my daily stats report. I am running with Windows Server 2008 R2, IIS 7.5 and ActivePerl 5.14.2. All versions are 64 bit. For robots, my system is routinely crawled by googlebot, msnbot and bingbot. These, however, only show up in Hosts but not in robots.
