Installer Command Line Options

This document is for corporate IT professionals and assumes knowledge of Command Lines, DOS prompts etc.

It is NOT REQUIRED for a normal install of any Simul8 Product.

Important: Using command line installation does not bypass Simul8’s machine specific software lock. The lock is present in all Simul8 products except “Network” editions, “Enterprise” editions and “Corporate” editions (with a Corporate Edition Agreement number).

You must use one of those editions if you want to use a deployment method that uses machine images (see separate technical fact sheet “Installing Simul8 via a Deployment Process”)

Command parameters

Install folder


Defines where the product should be installed on the destination machine. In many cases automated installs of Simul8 products cannot use the same folders as used by default in the wizard based installers. This is to prevent accidental overwrite of special installations. Therefore we recommend avoiding folders:

  • C:\Program Files\Simul8
  • C:\Program Files\Simul8 Viewer

Example: DIR:“ C:\Program Files\Simul8 for ME”

Required for a fully automated install.

License number

LIC:“[license number]”

Sets the license number of the product being installed. Not required (and should not be used) if your installer shows a default license number in wizard (non command line) usage. Some products are locked to specific license numbers that match your company's specific feature requests. Start the installer with no command line parameters and look at the last box on the second step in the wizard to see if you have a locked license number.

Example LIC:“1234-1234-1234” (The above is not a valid number)

Required for a fully automated install unless installer uses a locked license number.

Corporate Edition Agreement number

CEA:“[agreement number]”

Only relevant with a Corporate Edition Agreement.

Sets the Corporate Edition Agreement number for customers with a corporate edition agreement with Simul8 Corporation. Normally (when using the wizard based installer) this is entered via the separate S8CorpLicense.EXE installer, however the command line parameter CEA on the main installer will automatically run S8CorpLicense.EXE, invisibly, from the main installer.

Example CEA:“S12345678”

OEM License number

S8OEM:“[OEM license number]”

Only relevant for customers with an OEM (redistribution/software embedding) agreement.

Sets the OEM License number for customers with an OEM agreement with Simul8 Corporation.

Example S8OEM:“OEM12341234”

Silent Switch


When applied no wizards or progress bars are displayed. This parameter must always be the first on the command line, otherwise it is ignored.

A fully automated install (ie with LIC and DIR options) but without the silent switch will display progress bars etc but will not stop for wizard questions.

Example command line

C:> S8CSETUP.EXE /s DIR:“C:\Program Files\Simul8auto” LIC:“1234-1234-1234”

(Warning, the license number given in the above example is a dummy that will not work)


The installation wizard will be displayed unless the DIR and the LIC options are used (except that the LIC option is not required if the installer used by your organization uses a locked license number embedded in the installer – run the installer with no command line switches and inspect the last box on the second wizard display).
