Here are the steps to uninstall SAS 8.2:

Back up any necessary files. The following is a list of suggested
files, but it is not an exhaustive list:

   1. Script files in the Connect directory. For example,
      C:\Program Files\SAS Institute\SAS\V8\connect\saslink\tcpwin.scr
   2. Autoexec.sas.
   3. .sas files or data sets (.sas7bdat, .sd7, and so on) in
      the !sasroot directory.
   4. core.sas7bcat in C:\Program Files\SAS Institute\SAS\V8\
      core\sashelp\ directory.
   5. setinit.sss in C:\Program Files\SAS Institute\SAS\V8\core\sasinst\
      directory.

      Verify that the setinit.sss file has a current expire date in it.
      If not, locate an updated setinit file before you begin your
      installation.

   5. Go to the following directory to see which hot fixes have been
      applied:

      C:\Program Files\SAS Institute\SAS\V8\core\sasinst\hotfix

      Reapply them once your new installation is complete. When you go
      to reapply the hotfixes they might have been replaced with a newer
      one, if this happens apply the current hotfix.

      Here is an example of the hot fix audit file: 82bx08wn.aud.
