All of the files have been combined into one compressed (zipped) file, called isetlw20.zip
IMPORTANT NOTES TO USERS OF PREVIOUS VERSIONS
The file ISETLW.INI is no longer an include-able file; it has been changed to a standard windows initialization file. DO NOT !INCLUDE ISETLW.INI. It is recommended to install version 2.0 in a new directory to avoid overwriting any existing ISETLW.INI file.
If you have an ISETLW.INI file, it is recommended to rename it to a .STL file (such as ISETL.STL or ISETLW.STL) to avoid confusion between ini files and !include'able files. You may then have the file !include'd automatically at startup. See online help for details.
It is recommended to install version 2.0 in a separate directory to avoid naming conflicts and to insure maximum compatibility.
