The minimum recommended system configuration is Pentium II/233 with 96MB of RAM. You must have at least 175MB of free disk space for the typical installation (and, if not installing on Drive C:\, an additional 75MB free disk space on Drive C:\ to unpack the distribution). A complete installation requires 256MB of free disk space.
S-PLUS 6 for Windows uses a completely reengineered implementation of the S language. OBJECTS CREATED WITH S-PLUS 6 CANNOT BE USED WITH EARLIER VERSIONS OF S-PLUS. You should always run S- PLUS 6 in an S-PLUS 6 chapter as described in the detailed installation instructions on the CD; this ensures that your working directory contains only objects created in S-PLUS 6. You can use older objects in S-PLUS 6, but you should access them by attaching directories in a position other than 1 in the search list so that S-PLUS 6 does not accidentally write to them. If S-PLUS 6 does not write to an SV3 _Data directory, it can still be used by S-PLUS 2000 and earlier.
Do NOT install this release over any existing version of S-PLUS. Instead, designate a clean installation directory for S-PLUS 6 and proceed with the Setup program as described below.

















SET S_ELMHOST=<value>
Next, reboot your system. S-PLUS will be ready for use.
For NT 4 users, select the Environment tab. At the bottom of the window, you will see a Variable and a Value box. Type "S_ELMHOST" in the Variable box and the S_ELMHOST value from the licensing webpage in the Value box. Click "Apply" and then "OK".
For Windows 2000 users, you should see an Advanced tab with an Environment Variables button. Click on it. Under "User variables", click on New. For Variable Name, type "S_ELMHOST" (without the quotes) and for Variable Value, type the S_ELMHOST value from the licensing webpage, and click on the "OK" button. Repeat this for the "System variables." Lastly click on "Apply" back in the main Environment Variables box, and "OK" until you exit out of the panel.
S-PLUS is now ready for use.
The process is illustrated for Windows 2000 in the next three images.
