# Parameters for Silent Installation

You can use parameters to specify whether the plug-in is installed for all users or only for the current user on a Windows-based computer. Table Table 10-1. Parameters for silent installation describes the details of these parameters.

Table 10-1. Parameters for silent installation
Parameter | Description | Valid and Default Values
--- | --- | ---
INSTALLDIR | Specifies installation directory of the plug-in. | When ALLUSERS is `null`, the installation directory is set to: `%USERPROFILE%\AppData\Roaming\OpenText\PPM Center Add In for MS Project\` When ALLUSERS is `1`, the installation directory is set to the common program files folder, for example, `C:\Program Files\OpenText\PPM Center Add In for MS Project\`
ALLUSERS | Determines whether the plug-in is installed for all users or for the current user. Setting to `1` enables all users to use the plug-in. | Valid values: `1`, or `null` Default: `Null`, meaning that only the current user can use the plug-in.

To start the silent installation of the plug-in, run the following command together with the parameters in a command-line prompt:

`setup.exe /s /v"/qn <parameter1> <parameter2>"`

Caution: If you have to change the default installation directory when the ALLUSERS parameter is set to `1`, you must set the `INSTALLDIR` parameter to a directory that all users can access, for example, `C:\Program Files`.

### Examples

- The following command enables all users to use the plug-in:

  `setup.exe /s /v"/qn ALLUSERS=1"`

  This command does not specify the installation directory, meaning that the plug-in is installed to the common program files folder, for example:
  `C:\Program Files\OpenText\PPM Center Add In for MS Project\`

- The following command enables all users to use the plug-in. Also, the command specifies the installation directory to `C:\PPMCenter`. (Make sure that all users can access the `C:\PPMCenter` directory.)

  `setup.exe /s /v"/qn INSTALLDIR=\"C:\PPMCenter\" ALLUSERS=1"`

- The following command installs the plug-in to the `C:\APPSYS\PPMProject\` folder. Only the current user can use the plug-in.

  `setup.exe /s /v"/qn INSTALLDIR=\"C:\APPSYS\PPMProject\""`

- The following command installs the plug-in to the default installation directory. Only the current user can use the plug-in.

  `setup.exe /s /v"/qn"`
