On Windows, do not install the DB2 Universal Database Version 8 HTML documentation on a workstation or server where a DB2 Universal Database Version 7 (or earlier) product is already installed. The installer detects the earlier version and removes the earlier product.
A workaround does exist. If you need to install the DB2 Universal Database Version 8 HTML documentation on a machine where an older version of DB2 Universal Database is installed, you can manually copy the files and directories from the DB2 Universal Database Version 8 HTML Documentation CD, rather than using the installer. The DB2 Information Center and full text search will work, but you will not be able to apply any HTML documentation FixPaks.
