OpenOffice.org unveiled version 3.0 of its free office suite has been downloaded 3 million times in its first week, with about 80 percent of the downloads by Windows users.
The successful introduction of the open source office suite came despite the group's download servers being temporarily overwhelmed by demand for the new software last week.
Only 221,000 downloads by Linux users were recorded, leading John McCreesh, head of marketing for OpenOffice.org, to suggest a massive undercount. McCreesh said 90% of Linux users traditionally receive OpenOffice.org updates straight from their Linux distribution's vendor, which would explain the relatively low Linux count.
Many non-English versions of OpenOffice.org are also distributed by alternate Web sites, and OpenOffice.org is still widely distributed via free CD-ROMs in magazines, said McCreesh.
With the undercount included, OpenOffice.org 3.0 may already be installed on up to 5 million computers worldwide, McCreesh said in a blog post.
