Impact Acquire SDK Python
No More Network Connections Are Displayed

Symptoms

The following situation has been encountered:

  • After removing version 2.17.0 of any of the mvGenTL_Acquire*.msi packages and installing an older version (2.16.1 or smaller) no network connections are displayed in the "Network And Sharing Center" any more
  • Running ipconfig will still list the network interfaces correctly with their IP address however

Cause

This problem may occur when one of the following conditions is true:

Confirmed Bug In The Official Installer

  • You have installed a mvGenTL_Acquire*.msi package with version 2.17.0 on Windows Vista or newer
  • You have removed this installation again
  • You have installed a mvGenTL_Acquire*.msi package with version 2.16.1 or smaller on that very same system afterwards

Potential Bugs In Your Custom Installer

  • You have installed a 32-bit kernel driver on a 64-bit version of Windows
  • You have installed a version of the kernel driver that is not signed in a way it matches the signature requirements for the targeted version of Windows. See this section as well!

Resolution

  • Start the GigEConfigure on that system
  • Press the Remove Driver button
  • Start a administrator command shell on that system
  • type pnputil -e and press ENTER (since newer versions of Windows 10 -e has been superseded by /enum-drivers)
  • type pnputil -f -d (since newer versions of Windows 10 -e has been superseded by /delete-driver) and the name of the INF file containing the following data (the number between oem and .inf may vary):
    Published name :            oem36.inf
    Driver package provider :   MATRIX VISION GmbH
    Class :                     Network Service
    Driver date and version :   06/28/2016 3.0.1.55
    
  • remove every occurrence of mvGigECapture.sys or mvGigECapture2.sys from %windir%/System32/drivers and/or %windir%/SysWOW64/drivers (actually here you should NEVER see an instance of the filter driver thus this is a 32-bit folder on a 64-bit system and 32-kernel code is not supported on 64-bit Windows thus a buggy installation was the cause of this!).
  • restart the system
  • Start the GigEConfigure tool on that system
  • Press the Install Driver button
