Step 3: Reinstall Miniports

  2. Now, Open Command prompt and open C:deveconi386 directory for 32 bit windows and C:deviconia64 directory for 64 bit windows.
  3. Execute below mentioned commands for each miniport you have reinstalled. However, neither execute any of them twice nor execute command of miniport that is already installed, because it will create duplicate miniport and will conflict with the older one that is already installed.
