NetModem's MSI installers allows unattended installs,
either with or without a Configuration Snapshot.
Unattended installs simplify mass deployments by bypassing
the GUI interface prompts of the installer.
Basic Unattended installs
In order to pass command line options to an .MSI
installer, the MSIEXEC.EXE program needs to
The following MSIEXEC command line options
can be used for unattended installs:
Option - Description
/q or /quiet - Quiet mode, no user interaction.
Used for unattended installs.
/qb or /passive - Unattended mode, progress
/x or /uninstall - Uninstalls the product.
/l or /log - Logging Options. The following
log options are supported:
i - Status messages
w - Nonfatal warnings
e - All error messages
a - Start up of actions
r - Action-specific records
u - User requests
c - Initial UI parameters
m - Out-of-memory or fatal exit information
o - Out-of-disk-space messages
p - Terminal properties
v - Verbose output
x - Extra debugging information
+ - Append to existing log file
! - Flush each line to the log
* - Log all information, except for v and x options
MSIEXEC /i NetModemClient_330_x86.msi
or to see the progress bar during the install, use
the following command line:
MSIEXEC /i NetModemClient330.msi /qb
What is a Configuration Snapshot?
A configuration snapshot is a replica of the configuration
settings which are exported from the registry,
to simplify mass deployment of NetModem Client. It
can also be used to simplify applying global
changes to existing deployments.
The Configuration Snapshot file contains all the configuration
settings in NetModem Client, such as:
Creating a Configuration Snapshot
First install NetModem Client on one PC and configure
the Virtual COM ports and options as desired.
Next run the Snapshot Utility to create a configuration
snapshot (.REG) file.
The configuration snapshot file can then be used
on an MSIEXEC installer command line to install
the identical settings on other PC's during deployment.
Using the Configuration Snapshot Utility
You can use the snapshot utility to create a snapshot
of current NetModem Client configuration settings.
Download the snapshot utility here: NMCsnapshot.zip
Run NMCsnapshot.exe and it will prompt you to select
a path and filename. If a path is omitted,
the filename will be created in the current folder.
The filename should end with the .REG extention.
Once the .REG file has been created, its location
can be passed on the MSIEXEC command line
to automatically setup identical configurations of
NetModem Client during an unattended install.
MSIEXEC /i NetModemClient330.msi CONFIG="c:\NMC.REG"
The parameter: CONFIG="c:\path\filename.reg"
adds a snapshot configuration file to the registry.
The quote marks must be included only if the filename
contains spaces. The path to the snapshot
configuration file must be an absolute path (relative
paths are not permitted).
Note: MSIEXEC.EXE does not allow the /q
or /quiet option when passing a configuration
so the /qb parameter should be used, which
will provide a progress bar during the unattended
installation. To avoid the initial UAC elevation prompt,
the MSIEXEC command line should be
performed from an Administrator Command Prompt.
Unattended signed modem driver install/uninstall Utilities
Signed Modem drivers
can be installed unattended by using our Modem Driver Install Tool.
To remove existing modem drivers unattended, MS DevCon (Device Manager Console tool) can be used.
Download the Modem Driver Install Tool and DevCon here: ModemInstall.zip
Be sure to select the proper edition (x64 or x86) of the tools, to match the edition of Windows.
