Unattended installation

Unattended installation is provided to help streamline the installation process in bigger facilities. These tools are provided by Microsoft and allow starting installation on a remote computer. To support that feature, the Windows driver installer accepts license numbers, keys, users, and other information from command line. The command syntax is the following:

 msiexec /i <MsiFile> /qn USERNAME="<UserName>" COMPANYNAME="<CompanyName>" LICNUM="<LicenseNumber>" LICKEY="<LicenseCode>" 
Telos standard certificate must be in Trusted Publishers certificate store for unattended installation to not ask if you trust Telos as a publisher.

In driver versions before, the COMPANYNAME attribute was COMPANY and USERNAME attribute was USER.

Windows Vista and later: The silent install command must be started from the System account. (Start -> Run -> cmd then press Shift+Ctrl+Enter)

/qn invokes a silent install.

Starting from version, the installation can skip the initial launching of control panel if needed and the user knows what to do. To skip the control panel add the attribute DISABLECPL=1 to the msiexec command shown above.

If DISABLECPL=1 is used, lwr.conf will not be created automatically. To create it, you need to run the control panel manually and press the 'Apply' or 'Ok' button.

Starting from version, during installation MSI checks that the kernel module is totally unloaded from the system and if not, will halt the installation. To disable this checking, add the attribute SKIPKERNELCHECK=1 to the msiexec command.

Troubleshooting Installation Problems

Enable logging to a file. This can be used in conjunction with the msiecec commands above. The log file will be written in the location where the MSI file is launched from.

 msiexec.exe /i axiaipdr.msi.... /l*v axiaipdr_install.log

Windows PowerShell Script

Thanks to Nico van Zalk from our dealer, Triple Audio BV in the Netherlands for this Windows Power Shell script example. This is provided to you as an example to use if it is useful to you. It is provided without warranty or support from either Triple Audio BV or Telos Alliance.

Download the PowerShell Script example and other items needed by clicking here. Read the internal notes in the script for information on use. You will also need to place the installer for the driver in this same folder.

Then open a Powershell window and run the script.

Make sure your system has permission to run scripts.

The script assumes that the configuration file and certificate are in the same directory as the script runs from.
