INTRODUCTION

Windows 98 users: SAS Release 6.12 is experimental under Windows 98, therefore SAS does not support running 6.12 on Windows 98. The following instructions may be used, but are not specific to Windows 98.

In addition to this document, you should also have the following to install SAS:

1. SAS 6.12 CD-ROM (to install SAS)
2. SAS 6.12 Maintenance CD-ROM (to apply maintenance)
3. Update Diskette (to update SAS license information)

SYSTEM REQUIREMENTS

* Machines Supported
Any PC using an Intel or Intel-compatible 80386 33MHz or higher CPU is supported.  Performance can be improved with a 33MHz or faster 80486 or Pentium machine.

* Floating Point Unit or Math Coprocessor
A floating point unit or math coprocessor (e.g., the Intel 80387 for 386 machines) is STRONGLY recommended.  Be sure to install a math coprocessor with the appropriate MHz rating.  A floating point unit or math coprocessor is assumed present in the PC and the SAS System is optimized for its presence.  Microsoft Windows provides floating point emulation software with decreased performance in the absence of a floating point unit or math coprocessor.

* Memory Requirements
16MB minimum, more for improved performance.  For Base SAS software, 15 MB of swapfile space is required.  For other components, particularly SAS/AF software and SAS/EIS software, 25 or more MB of swapfile space is required.

INSTALLATION PROCESS

The installation of SAS consists of three steps. All steps must be completed to run SAS.

STEP 1: SAS System Installation Process

Insert the SAS 6.12 CD-ROM into the source drive.  If the AutoPlay feature enabled, Setup will start and you can skip the remainder of this section.  If AutoPlay is not enabled, select Start and then Run .

   1. Type :\SAS\Setup where "source drive" is the letter of the CD-ROM drive (eg. D:\SAS\SETUP).
   2. Select SAS System Setup.
   3. Following the instructions on the screen.*

		Setup is ready to update your licensing information.
	Update license (setinit) information?  [recommended]

		There appears to be a problem with your setinit.sas file!  
	Would you like to correct the file now?

		Licensing process has been terminated by the user.

*See Additional Installation Information.

STEP 2: SAS Maintenance Installation

Insert the SAS 6.12 Maintenance CD-ROM into the source drive.  If the AutoPlay feature enabled, Setup will start and you can skip the remainder of this section.  If AutoPlay is not enabled, select Start and then Run .

   1. Type :\SAS\Setup where "source drive" is the letter of the CD-ROM drive (eg. D:\SAS\SETUP).

   2. Following the instructions on the screen.

STEP 3: Updating SAS License Information (Changing the Expiration Date) Refer to the Instructions for Updating SAS License Information (Changing the Expiration Date)-PC/SAS 6.12 for Windows 95, Windows 98 and Windows NTInstructions for Updating SAS License Information (Changing the Expiration Date)-PC/SAS 6.12 for Windows 95, Windows 98 and Windows NT.

SAMPLE INSTALLATION CONFIGURATIONS

Typical
You want to install all of the components on the SAS System CD, but do not need the Help files, Sample files, or Test programs.

Compact
You are only interested in Data Step functionality.  This will save hard drive space but no procedures will be available.

Custom
Select all of the components if you want to install all of the components from the SAS System CD, including Help files, sample files, and test programs.
Select only the components you want installed if you want to install only some of the components from the SAS System CD to your local hard drive, or to a network location for personal use.

Custom with Options for each component
You want to install selected components and define the options for each component installed from the SAS System CD to your local hard drive or to a network location for personal use.  Select the components so that a check appears in the box beside the component name.

To install only parts of a component, select Options after highlighting or selecting a component name.  From the Options window you can then deselect the parts/options of a component that you do not want installed.

CD or Client and Full install
You want to access the SAS System directly from the CD-ROM or from a shared network location provided a valid site license has been applied.  Only system files and registry information are installed locally to your disk drive.  If you do not have a valid site license applied you will need to perform a Selective Client install selecting the CORE component.  After the component is installed, you will be prompted to supply licensing information.

CD or Client and Selective install
You want to run the SAS System from a CD or network but would like to increase the speed of SAS/CORE or some other components.  Select the components so that a check appears in the box beside the component name that you want installed locally.  The components you select here will run more efficiently since they will be accessed directly from the hard drive you install them to.

CD or Client and Selective install with Options for each component
You want to run the SAS System from a CD or shared network location, and would like to increase the speed of the CORE of the SAS System, or some other components but do not want all of a particular component installed.  Select the components so that a check mark appears in the box beside the component name.  To select only parts of a component, select Options after highlighting or selecting a component.  From the Options window you can then deselect the parts/options of a component that you do not want installed.

DESTINATION FOR SAS INSTALLATION

A default destination is set to a hard drive location which you can change by selecting Change Folder. [Note: There needs to be enough space on the drive you choose.] After you choose an installation type and a destination location, the Setup program determines if you have enough disk space to install the SAS System. If you do not have enough disk space, you can specify a different destination. Setup will also determine if a copy of SAS exists at the destination location. You can remove the copy of SAS or modify it during installation.

REMOVING OR MODIFYING EXISTING SAS FILES

SAS Setup will detect any version of the SAS System present in the selected installation directory.  You will have the opportunity to purge the existing copy, modify it, or select another directory in the Existing SAS Files Detected window. Your options are as follows:

Purge Erases ALL components, files, and subdirectories under the destination directory.  This option also erases any user files stored in this location.

Modify Adds selections to the existing SAS directory.  No components will be deleted.

Caution! If you select Purge note that ALL files under the selected directory are removed.  SAS Setup notes this fact twice to avoid any confusion.

Caution! Selecting Yes purges all files and directories below the specified installation destination.

Once the purge has been selected and successfully completed, the actual file copying process of the SAS System files will begin into the selected installation destination.  If you select Purge, you may receive an error message indicating that Setup could not delete the files from this directory.  Check that a process, including a MS-DOS prompt, is not running from this directory.  If you cannot find another process using this directory but the directory is empty, then it is safe to ignore the message and continue.

Select Abort if you want to abort the purge.  Select Yes if you want to retry the purge, and select No if you want to continue and ignore the files that the system could not purge.

SAS PROGRAM GROUP (SAS icons)

When installing under Windows 95, a shortcut is added to the Start buttons Programs menu.  If you installing under Windows NT, you will be asked in which Program Manager Group you want the SAS System icon installed.  By default, a program folder named The SAS System will be created for you.

INSTALLATION REVIEW

At this point, Setup has enough information to begin installing SAS components.  You need to review the installation choices as shown in the Current Settings box.  Select Next to begin installing the SAS System, Back to return to previous screens, or Cancel to exit Setup.

ADDITIONAL INSTALLATION OPTIONS

If the SAS Setup program determines that additional installation options are available, windows for the additional installation options will be displayed.  After all of the SAS System files have been copied, each of these installation options will launch another setup program.  Once these external setup programs are finished, you will be returned to SAS System Setup.

* Installing the SAS Viewer
When installing Base SAS software on Windows 95, Setup will prompt you to install the SAS System Viewer.  The SAS System Viewer is intended for the Windows 95 Explorer environment as a Quick Viewer for SAS data sets and catalogs.  The application lets you view the contents of SAS data set and catalog files without using the SAS System or requiring the SAS System to be installed on your machine. You are free to distribute this program to allow other people to view your SAS data.  For more information, view the Readme.wri file using Microsoft Word either directly from the installation media in the SASVIEW/DISK1 folder, or after installation from the destination directory where you installed the SAS Viewer.  The default is C:\Program Files\The SAS Viewer\Readme.wri.

* Installing 16 bit and 32 bit ODBC Drivers The SAS ODBC Driver allows you to access, update, and manipulate SAS data from your favorite ODBC-compliant applications, such as Microsoft Access, Microsoft Excel, Visual Basic, and PowerBuilder.  The SAS ODBC Driver provides read access to databases such as IBM DB2 and ORACLE via SAS/ACCESS software running on remote SAS servers.  Further, SAS views can be defined to join database tables from different vendors, creating a virtual data warehouse for your ODBC-enabled applications.

You should install either the 16 or 32 bit version of the SAS ODBC Driver depending on the version of Windows you are running, and whether your ODBC applications are 16 or 32 bit.

On Windows 95 you can install both the 16 and 32 bit drivers depending on your application needs.  16 bit applications can use both 16 and 32 bit drivers and hence can see data sources defined by each type of driver.  32 bit applications can only use 32 bit drivers and therefore can only see data sources defined to the 32 bit drivers.  This occurs because Windows 95 allows thunking (16 to 32 bit translation) from 16 to 32 bit applications but not from 32 to 16 bit applications.  The ODBC Driver Manager handles all thunking issues.
