Loads a memory-resident program into memory. Use the systemroot\System32\Config.nt file, or the equivalent startup file specified in a program's program information file (PIF), to specify the program to install.


install=[Drive:][Path] FileName [CommandParameters]


[Drive:][Path] FileName : Specifies the location and name of the memory-resident program you want to run.

CommandParameters : Specifies parameters for the program you specify for FileName.

/? : Displays help at the command prompt.


Use install to load a memory-resident program into memory just prior to starting the application that requires the memory-resident program. If a memory-resident program is loaded into memory using the Autoexec.nt file, the memory-resident program will be loaded into memory every time the command prompt is started, wasting memory.

Do not use install to load programs that use environment variables or shortcut keys or that require Cmd.exe to be present to handle critical errors.


To load a program into memory in the Config.nt file, type the following:


Formatting legend



Information that the user must supply


Elements that the user must type exactly as shown

Ellipsis (...)

Parameter that can be repeated several times in a command line

Between brackets ([])

Optional items

Between braces ({}); choices separated by pipe (|). Example: {even|odd}

Set of choices from which the user must choose only one

Courier font

Code or program output

Command-line reference A-Z
