  3. Quit all programs that are running, including any antivirus programs.
Try to upgrade or install Internet Explorer. If you are unsuccessful, proceed to the following method.

Method 2: Limit RAM to 256 MB

If you have more than 256 megabytes (MB) of random-access memory (RAM) installed, remove or limit the RAM that Windows uses to 256 MB or less.

Microsoft Windows 95

If you are running Windows 95, you can use a RAM drive to limit the RAM that is available to Windows.

For additional information about how to use a RAM drive to limit the available memory, click the following article number to view the article in the Microsoft Knowledge Base:
142546 How to use a RAM drive to troubleshoot memory

Windows 2000 or Windows NT 4.0

If you are running Windows 2000 or Windows NT 4.0, edit the Boot.ini file to limit the memory that is available to Windows. Add the following switch to the ARC path in the [Operating System] section of the Boot.ini file, where amount of RAM is the RAM that you want to allow Windows to use.
/MAXMEM=amount of RAM
For example, the following ARC path limits Windows to 256 MB of RAM:
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Server"  /fastdetect /MAXMEM=256
				
NOTE: The Boot.ini file is a hidden file located in the root folder of the boot drive.
