If using Internet Explorer, you have both options below; if using
Netscape Navigator or HotJava, you have only the "Save As" option
below.
Open - This enables you to install the JRE without leaving a compressed
file on your hard disk.
Save As - This saves the downloaded file without
installing it. It will be saved at C:\ by default. Check
that you have downloaded the entire file by comparing
the size of the file you downloaded with the expected size:
Win32 JRE for all locales (internationalized):
jre-1_2_1_004-win-i.exe
12,524,941 bytes
Win32 JRE for U.S. English only:
jre-1_2_1_004-win.exe
9,570,470 bytes
After downloading this file, you can double-click on its icon to run the
installer. Follow the instructions the installer provides. When done with
the installation, to recover more disk space, delete the bundle you
downloaded.
