The Access Snapshot Viewer is an additional component in Office (multiple versions). It depends on how Office has been installed as to whether users will already have it installed or if it will auto install for them. It can also be freely installed from Microsoft.
Create an access report and select the File/Export menu to create an snp file and copy this file into a document library.
(you can automate the publishing of reports by following this article http://office.microsoft.com/en-us/access/HP052612171033.aspx )
